Where Did You Go - by Jeneane O'Riley

Here is a summary with spoilers of Where Did you Go

The book picks up immediately where Book 2 left off. Calypso (Cal), along with her mate and almost-husband Mendax, and her best friend and tether Eli, embark on their journey to Moirai, where Cal’s father, Zef, awaits. Their mission is twofold: to speak with the gods and break one of Cal’s bonds, as she cannot remain tied to both Mendax and Eli. But for Cal, this journey holds an even greater purpose—revenge. She has long awaited the moment to kill her father for what he did to her family.

The journey is grueling, taking a toll on all of them. But what weighs on Cal most is her unresolved feelings for both fae. Meanwhile, Eli and Mendax are relentless in their attempts to sway her decision, each desperate to be the one she chooses. Eli, however, takes it to a dangerous level—when he realizes a monster is about to attack, he deliberately holds Cal back, knowing it will go after Mendax first. His gamble nearly succeeds. Mendax barely survives.

Exhausted and hungry, the trio takes shelter in a cave. When Cal wakes, she finds Mendax watching over her, and a moment of passion unfolds between them. But when they come back to reality, they realize Eli is gone. Together, Cal and Mendax continue toward their destination and eventually catch up with Eli. However, they quickly discover that this is not where they will meet Zef and the gods—only where they will receive their next clue.

That clue lies beneath a frozen lake, trapped under thin ice littered with corpses. It is Cal who must retrieve it. The message reveals their next step: they must find The Weathered, a nature goddess, and convince her to start a flood.

During this time, Cal makes a devastating realization—both Eli and Mendax have been secretly feeding her power. Being bound to two fae is rapidly deteriorating her, and though they have been trying to keep her stable, it is draining them as well. Even worse, they begin to notice a strange pattern—glass butterflies have been following them.

As they take a moment to recover, Eli and Cal share a heart-to-heart. Eli first pleads with her not to kill her father, urging her to hear him out first. Then, he confesses something unexpected—he loves Cal, but not in the same way Mendax does. There is no romantic connection between them, only a deep, unbreakable friendship. To Cal’s relief, she feels the same way. However, Eli asks her not to tell Mendax just yet—he wants to mess with him a little. Unfortunately, his teasing goes too far. Mendax, overcome by possessiveness, lashes out, and the two begin fighting again.

In the following chapters, we see both fae’s perspectives, and despite their animosity, a reluctant respect begins to form between them.

Eventually, they locate The Weathered, who possesses the power to summon floods. Eli and Mendax manipulate her emotions, convincing her to unleash one. The flood comes fast—too fast. As they flee, they encounter a figure that Eli, to their surprise, is thrilled to see—Zef.

Before meeting with Zef, Eli and Mendax strike a secret bargain: Eli owes Mendax a favor—one that can be claimed at any time, in any place, for anything.

The long-awaited reunion between Cal and Zef is brief and tense. She learns that the glass butterflies were his doing—a beacon meant to guide them. When she finally unleashes some of her fury on him, Zef shows remorse. But their conversation is cut short as the flood worsens. They barely manage to escape onto a boat, riding out the waters—until they reach a cliff. Zef vanishes, and in the chaos, Cal falls into the current, somehow tumbling through a portal.

When she awakens, she is back in the human realm—standing at the exact entrance she used to first enter the Unseelie Court. Before she can process what has happened, a letter is delivered to her. It presents a choice:

1. Stay in the human world. The bond and tether with the fae will break. She will never see them again. But she will be free.

2. Step back through the portal. Reunite with them. Face the trials the fates have laid out for her.

Without hesitation, she steps through.

Reunited with Eli and Mendax, their journey resumes—this time, with a destination. They arrive at their next location only to learn they must now find a book. While searching, Mendax confronts Cal, sensing that she has been different since their reunion. He presses her for the truth—and she finally admits it. She is planning to sacrifice herself to save both him and Eli.

Mendax is furious. He forces her to promise that she won’t. And not only that—he makes her swear that if they survive, they will finish the bond and get married. Cal agrees.

When they find the book, they realize it isn’t just a book—it’s a portal. It transports them directly to Moirai.

Upon arrival, they separate to rest, but Cal is led to Zef. Their conversation is a turning point. Though she still feels betrayed by him, Zef insists that he loves her. However, his sorrow deepens when he hears of her choice to return to the fae. The fates' plan is clear—they will break her bonds and let Eli and Mendax continue on. But Cal will die.

Cal accepts this—after all, it means she will finally pass on to the Elysium Fields.

Except Zef tells her she won’t.

Her sister, Adrianna, has not reached Elysium. She is trapped in Tartarus. A piece of her soul never reunited with the rest—it remains hidden in the ashes that Cal has unknowingly carried around her neck this entire time.

Hours before the fates’ decree, Mendax and Cal reunite at Zef’s home—both having snuck in separately, both intending to kill Zef.

Cal decides against it.

Instead, the three perform a ritual. Cal willingly gives up her animal-talking powers, binding them with Adrianna’s ashes so her sister can finally pass on to Elysium. In the process, they uncover another truth—Cal’s mother was not human. She was a changeling.

Before they leave, Zef presents Cal with a dagger. Whoever wields it and kills someone will transfer that person’s power to Cal.

Then, Mendax confesses his own secret. He made a deal with the fates. He convinced them to break Eli’s bond—but in exchange, he will be the one to die.

Cal is devastated. But it’s too late. The fates are waiting.

When they arrive, the fates reveal their plan: Cal is to die.

But Mendax has an alternative plan—his sacrifice instead.

However, neither of those plans come to pass.

Because the fates choose a third option—one that Eli created.

The tether will be severed, but instead of Cal or Mendax, Eli will die.

Before they can stop it, the decision is made. Eli is gone.

The pain is unbearable. Mendax, still bonded to Cal, feels only a fraction of her grief, but it is still the worst agony he has ever known.

And then, in the epilogue, we return to Eli’s POV.

He wakes up.

And the first thing he sees… is a familiar pair of brown eyes.
