The Exquisite Torment of Loving Your Enemy by Brigitte Knightley

Here is a summary with spoilers for The Exquisite Torment of Loving Your Enemy by Brigitte Knightley

Osric Mordaunt, a Fyren assassin, and Aurienne Fairhrim, a Haelan healer and researcher, have already crossed the line from outright hostility into an attraction neither of them wants to acknowledge. Osric is still suffering from seith rot, a degenerative disease that is destroying his seith system and will eventually kill him. Aurienne has been treating him through an experimental healing method based on the Old Ways, with the treatments taking place around the full moon. At the same time, Osric has been providing financial support for Haelan efforts to combat Platt's Pox, a disease that has killed or permanently damaged thousands of children throughout the Tīendoms. Their relationship is still officially transactional: Aurienne is treating his illness, and Osric is funding work that matters to her. Neither is willing to admit that the arrangement has become personal.

In the beginning, Osric is already deeply affected by Aurienne, although he continues to insist to himself that she is simply a means to an end. Aurienne is equally determined to treat their relationship as a professional one. She researches the history of the Dreor Order because the evidence from the Pox investigation suggests that the disease may be connected to the long-extinct or nearly extinct Order of death-knights. The possibility is disturbing because Dreor soldiers are associated with losing their minds and becoming creatures capable of following orders without normal human judgment. Aurienne begins looking into their history, rituals, recruitment, and methods while continuing Osric's monthly treatments.

Their next full-moon treatment takes them to the Færwundor, a Druidic stronghold. Aurienne had previously been reluctant to accompany Osric there because he is wanted by the Druids after killing their leader as an assassin. They nevertheless travel there together because the location is connected to the Old Ways and may provide another opportunity to treat Osric's seith rot. Their attempt goes badly. They use a shadow-walk and encounter the aftermath of a massacre: the Druids have been slaughtered, and one surviving Druid is able to tell them that the Dreor are coming. The two flee through an underground river while trying to survive the consequences of the failed ritual. During the escape, Aurienne's seith enters Osric's system in a way that appears to replenish rather than simply heal him. They nearly drown, but the experience provides further evidence that the treatment is doing something to his damaged seith channels.

After escaping, they take refuge at a small inn. The circumstances force them into close physical proximity and basically share the same small bed, and Osric becomes increasingly aware that Aurienne feels safe with him despite everything she knows about his profession. Their relationship has changed enough that physical affection begins to appear in small ways before either of them is prepared to acknowledge what it means. Meanwhile, the treatment is producing measurable results. One of Osric's damaged seith nodes eventually regenerates, which is a major development because regeneration of a node lost to seith deterioration has not previously been documented. The Old Ways, which Aurienne initially regarded as superstition rather than legitimate medicine, are producing results that conventional Haelan medicine cannot explain.

The fragile peace between them is interrupted when Tristane, the Fyren warchief and Osric's superior, attempts to enter Swanstone, the Haelan stronghold. She is caught and captured. Because Tristane is a Fyren and has entered Haelan territory, she is placed in danger of execution. Osric wants to rescue her, but Aurienne has anticipated that he will attempt exactly that. She uses a failsafe built into his seith system to prevent him from going after Tristane. From Aurienne's perspective, allowing Osric to storm Swanstone would put him and everyone else at risk. From Osric's perspective, she has deliberately prevented him from saving someone he considers family. He is furious. Their trust, which had been growing steadily, fractures.

Tristane's situation eventually becomes a major source of conflict between Osric and Aurienne. Osric understands that Aurienne was acting according to her Haelan principles, but he cannot easily forgive her for manipulating his body to stop him. Aurienne, meanwhile, believes Osric's loyalty to the Fyren Order makes him impossible to trust completely. Their next treatment takes place under strained circumstances, and they fall back into their familiar insults and arguments. Even so, Osric recognizes that Aurienne's actions came from a desire to keep him alive. Their hostility is no longer genuine in the way it was at the beginning of the first book.

Their next full-moon treatment takes them to the Hotel Llawgnychu, where they have to pose as a married couple. The situation forces them to behave publicly as though their relationship is already something intimate and established. During the treatment at Enfys Falls, Aurienne performs a prismatic healing inside a rainbow. The treatment produces another significant improvement in Osric's condition. His seith rot is no longer merely being slowed; the damage is beginning to reverse.

Afterward, Osric and Aurienne become drunk together beside a lake. Away from the formal structure of their work and the arguments that normally protect them, they begin speaking honestly about themselves. Aurienne's resistance to Osric is connected partly to the damage caused by someone she loved previously, while Osric's resistance comes from his conviction that someone like Aurienne could never genuinely love someone like him. They finally stop pretending that their attraction is imaginary. They kiss, continue the physical relationship they have been resisting, and ultimately sleep together. Their relationship changes permanently after this point. They are no longer simply two enemies working together; they are lovers, although neither is immediately comfortable saying that aloud.

After returning home, Aurienne examines Osric's condition and confirms that the seith rot has receded further. Osric is genuinely pleased by her reaction to the discovery, and he begins acting less like someone who is paying for a service and more like someone who wants to make Aurienne happy. He continues helping her research without demanding anything in exchange. The distinction between their original bargain and their actual relationship has effectively disappeared.

The investigation into Platt's Pox becomes more disturbing when Osric investigates Brackenbury Asylum. He discovers that children are being deliberately infected with the Pox and that nurses have been kidnapped. The asylum is effectively being used as part of a Dreor operation. The infected children are not simply victims of an epidemic; they are being prepared for something. The evidence supports Aurienne's earlier theory that the Pox is being deliberately spread to create future Dreor soldiers.

Aurienne becomes involved in the investigation as well. At Brackenbury, she is confronted with circumstances that force her to violate the absolute principle of the Haelan Order: "Harm to none." When she has to fight the wightlings created through the Dreor process, she uses her seith offensively. This is a major turning point for her because she has spent her life believing that healing and nonviolence distinguish the Haelans from the more violent Orders. She discovers that refusing to cause harm can itself prevent her from protecting people. Her moral certainty begins to change.

The investigation also begins connecting the Dreor conspiracy to the political leadership of the Tīendoms. The Pox is not simply being spread by a rogue group operating independently. Several sovereigns are implicated in working with the Dreor. Their goal is to exploit the infected population and create an army of wightlings: people whose minds have been destroyed so that they can function as obedient soldiers. The conspiracy explains why the Pox has been allowed to spread and why children are particularly important to the scheme.

Osric and Aurienne continue their relationship while investigating the conspiracy. Their banter becomes more affectionate, and Osric is increasingly protective of Aurienne. The book deliberately keeps their romance intertwined with the medical investigation: each full-moon treatment brings another improvement in Osric's condition while also forcing them to become more emotionally intimate. The treatment eventually reaches the point where the degeneration in his cervical seith channels begins reversing rather than simply slowing.

They also attend the opera together. What begins as an outing becomes another escalation in their relationship. The public setting contrasts with the secrecy surrounding their relationship, and the encounter becomes one of the book's major romantic turning points. Their physical relationship is no longer something that can easily be dismissed as an accident or a consequence of being trapped together. They are choosing each other.

The situation with the Fyren Order eventually becomes dangerous again. Osric's growing attachment to Aurienne places him in conflict with his own Order because the Fyren have interests that can directly threaten the Haelans. Tristane remains an important figure in this conflict, and Osric is forced to reconcile his loyalty to the woman who raised and commands him with his growing loyalty to Aurienne. His choices increasingly demonstrate that he is no longer willing to treat the Fyren's interests as automatically more important than Aurienne's safety.

The next healing brings another significant breakthrough. By the Thunor moon, Osric's seith deterioration has undergone a wholesale reversal. The disease that was supposed to be terminal is no longer visible in his system. The treatment has gone far beyond slowing his death; it has effectively reversed the damage. Aurienne's work has accomplished something previously considered impossible. The treatment also reveals that the relationship between their two seith systems is important, because repeated exposure to Aurienne's seith appears to have contributed to Osric's recovery.

Their relationship nevertheless becomes threatened by the reality of their Orders. Aurienne is still a Haelan, bound by the expectations of an Order dedicated to healing and nonviolence. Osric is still a Fyren assassin whose career has been built on killing people for money. Both of them understand that their relationship violates the boundaries they were raised to accept. Osric in particular becomes convinced that loving Aurienne will eventually hurt her. His instinct is therefore to retreat emotionally even while he continues protecting her physically.

The investigation eventually leads them toward the larger Dreor threat and the coming attack on Swanstone. The conspiracy has progressed beyond secret experiments. The Dreor forces are preparing to use the wightlings against the Haelans. Swanstone becomes the critical target because it houses vulnerable patients, researchers, and children and because the Haelan Order is central to the fight against the Pox. The impending assault turns the personal conflict between Osric and Aurienne into part of a much larger war.

As the threat closes in, Osric and Aurienne are forced to confront the possibility that they may not survive. Osric's instinct is to protect Aurienne even at the cost of his own life. Aurienne, meanwhile, has moved far beyond the woman who originally regarded Osric as an immoral assassin who should never have been allowed into her laboratory. Her actions throughout the investigation have shown that she trusts him, depends upon him, and loves him despite the contradiction that creates with everything she has believed about the Fyren Order.

The Dreor attack on Swanstone finally begins. The defenders are badly outnumbered, and the fortress is placed under direct assault. Osric fights alongside the people he once would have considered enemies, including Haelans, while Tristane and other Fyren become unexpected allies in the defense. The battle is fought around the fortress and the vulnerable children inside it. The Dreor use their wightlings as weapons, making the battle particularly brutal because the defenders are fighting people who have been stripped of their minds and turned into soldiers.

Osric nearly dies protecting Aurienne. His willingness to put himself between her and the attackers makes the extent of his feelings impossible to deny. He has spent much of the book believing that loving Aurienne is something he should resist because their Orders make the relationship impossible. During the battle, his actions demonstrate that he has already chosen her regardless of the consequences. The defenders eventually survive the assault, but there are deaths and lasting consequences from the attack.

After the battle, the political conspiracy is exposed and the conflict expands beyond Swanstone. The sovereigns involved with the Dreor are revealed, and the Tīendoms move toward open war. The Dreor threat is no longer something that can be dealt with through a small investigation. The surviving Orders have to decide how they will respond to the people responsible for deliberately creating the Pox and the wightling army.

Osric and Aurienne still struggle to articulate what they have become to one another. Osric believes that his identity as a Fyren makes him fundamentally wrong for Aurienne, while Aurienne has to accept that her definition of what a Haelan should be is no longer sufficient to explain her own choices. Their relationship has forced both of them to recognize that the Orders do not completely define the people who belong to them.

The final healing takes place during the seventh moon at the Fairy Glen, connected to the Monafyll Stone and the Old Ways. By this point, Osric's seith rot has effectively been reversed. Aurienne then turns the healing inward and treats herself. The emotional significance of this is tied to her past and to the hagstone necklace she has carried as a reminder of previous betrayal and emotional protection. She breaks the necklace and throws it into the pond, symbolically abandoning the defensive identity she has carried throughout the story.

Osric arrives at the Fairy Glen, and the two finally stop avoiding the truth about their relationship. They confess that they love each other. The language that previously reduced their relationship to a transaction — Osric treating Aurienne as a "means to an end" and Aurienne treating him as a dangerous problem to be managed — is finally abandoned. They choose each other without pretending that the relationship is temporary, accidental, or merely the result of the healing treatments.

The first epilogue takes place at Swanstone during a ceremony honoring those who fought during the attack. Osric is invited as a guest of honor despite being a Fyren. Tristane is invited as well, demonstrating the temporary truce between the Orders. Tristane accepts the Haelans' gratitude for the Fyren's assistance and even approves of the memorial statue of the hellhound. The ceremony recognizes the contributions of the different Orders that helped defend Swanstone.

The second epilogue is presented as Aurienne's research notes. She documents Osric's treatment as a medical case study, recording the progression from severe seith degeneration to complete reversal. The seven treatments correspond with the Old Ways and the full moons. Her notes record that Osric initially showed no measurable change, followed by slowed degeneration, regeneration of a damaged node, reversal of demyelination, and finally complete disappearance of the disease. She also notes that her own seith markers may have contributed to the process and that repeated exposure to Haelan seith may be therapeutically significant.

Aurienne's notes also make clear that the treatment has implications beyond Osric. If sustained exposure to Haelan seith can reverse advanced seith degeneration, the discovery could potentially change treatment for other patients with similar diseases. She acknowledges that the method was experimental and would not meet normal medical or ethical standards, but the results are unprecedented. She credits Osric's insistence on pursuing the treatment, Xanthe's support, and Professor Widdershins's research into the Monafyll Stone for helping make the discovery possible.

The final epilogue returns to Osric and Aurienne as a couple. Osric has committed himself to making different choices, and he gives up possessions and resources to help with the coming conflict. Rosefell Hall becomes a place where people from different Orders can work together rather than remaining divided by the old boundaries between them. He also returns his signet ring to Aurienne as a promise. At the same time, Aurienne continues investigating the Monafyll Stone and realizes that it may be an unmapped waystone capable of connecting their world to somewhere else. An acorn from the Færwundor oak also begins to grow, providing a final indication that something destroyed may be beginning again.
