With furious looks at everyone, he stomps across the grass and speaks a few words. The enchantment begins to dissipate. Heather begins to cry anew, though, as her humanity returns. Huge sobbing gasps shake her.

“I want to go,” she says finally in a quavering, wet voice. “I want to go home right now and never come back.”

Vivi should have prepared her better, should have made sure she always wore a charm—or better yet, two. She should never have let Heather wander off alone.

I fear that, in some measure, this is my fault. Taryn and I hid from Vivi the worst of what it was to be human in Faerie. I think Vivi believed that because her sisters were fine, Heather would be, too. But we were never fine.

“It’s going to be okay,” Vivi is saying, rubbing Heather’s back in soothing circles. “You’re okay. Just a little weirdness. Later, you’re going to think it was funny.”

“She’s not going to think it was funny,” I say, and Vivi flashes me an angry look.

The sobbing continues. Finally, Vivi puts her finger under Heather’s chin, raising her face to look fully into it.

“You’re okay,” Vivi says again, and I can hear the glamour in her voice. The magic makes Heather’s whole body relax. “You don’t remember the last half hour. You’ve been having a lovely time at the wedding, but then took a spill. You were crying because you bruised your knee. Isn’t that silly?”

Heather looks around, embarrassed, and then wipes her eyes. “I feel a little ridiculous,” she says with a laugh. “I guess I was just surprised.”

“Vivi,” I hiss.

“I know what you’re going to say,” Vivi tells me under her breath. “But it’s just this one time. And before you ask, I’ve never done it before. But she doesn’t need to remember all of that.”

“Of course she does,” I say. “Or she won’t be careful next time.”

I am so angry that I can barely speak, but I need to make Vivi understand. I need to make her realize that even terrible memories are better than weird gaps or the hollow feeling that your feelings don’t make sense.

But before I can begin, the Ghost is at my shoulder. Vulciber, beside him. They are both in uniform.

“Come with us,” the Ghost says, uncharacteristically blunt.

“What is it?” I ask them, my voice sharp. I am still thinking about Vivi and Heather.

The Ghost is as grim as I’ve ever seen him. “The Undersea made its move.”

I look around for Oak, but he is where I left him moments before, with Oriana, watching Heather insist that she’s fine. A small frown creases the space between his brows, but he seems otherwise utterly safe from everything but bad influence.

Cardan stands on the other side of the green, near where Taryn and Locke have just come back from swearing their vows. Taryn looks shy, with roses in her cheeks. Folk rush over to kiss her—goblins and grigs, Court ladies and hags. The sky is bright overhead, the wind sweet and full of flowers.

“The Tower of Forgetting. Vulciber insists you ought to see it,” the Bomb says. I didn’t even notice her walking up. She’s all in black, her hair pulled into a tight bun. “Jude?”

I turn back to my spies. “I don’t understand.”

“We will explain on the way,” Vulciber says. “Are you ready?”

“Just a second.” I should congratulate Taryn before I leave. Kiss her cheeks and say something nice, and then she’ll know I was here, even if I had to go. But as I look toward her, evaluating how swiftly I can do that, my gaze catches on her earrings.

Dangling from her lobes are moons and stars. The same ones I bargained for from Grimsen. The ones I lost in the wood. She wasn’t wearing them when we got in the carriage, so she must have got them…

Beside her, Locke is smiling his fox smile, and when he walks, he has a slight limp.

For a moment, I just stare, my mind refusing to acknowledge what I’m seeing. Locke. It was Locke with the riders, Locke and his friends on the night before he was to be married. A bachelor party of sorts. I guess he decided to pay me back for threatening him. That, or perhaps he knew he could never stay faithful and decided to go after me before I came back for him.

I take one last look at them and realize I can do nothing now.

“Pass the news about the Undersea on to the Grand General,” I tell the Bomb. “And make sure—”

“I’ll watch over your brother,” she reassures me. “And the High King.”

Turning my back on the wedding, I follow Vulciber and the Ghost. Yellow horses with long manes are nearby, already saddled and bridled. We swing up onto them and ride to the prison.

From the outside, the only evidence that something might be wrong is the waves striking higher than I’ve ever seen them. Water has pooled on the uneven flagstones.

Inside, I see the bodies. Knights, lying pale and still. The few on their backs have water filling their mouths as though their lips were the edges of cups. Others lie on their sides. All their eyes have been replaced with pearls.

Drowned on dry land.

I rush down the stairs, terrified for Cardan’s mother. She is there, though, alive, blinking out at me from the gloom. For a moment, I just stand in front of her cell, hand on my chest in relief.

Then I draw Nightfell and cut straight down between bar and lock. Sparks fly, and the door opens. Asha looks at me suspiciously.

“Go,” I say. “Forget our bargains. Forget everything. Get out of here.”

“Why are you doing this?” she asks me.

“For Cardan,” I say. I leave unsaid the second part: because his mother is still alive and mine is not, because even if he hates you, at least he should get a chance to tell you about it.

With one baffled look back at me, she begins to ascend.

I need to know if Balekin is still imprisoned, if he’s still alive. I head lower, picking my way through the gloom with one hand against the wall and the other holding my blade.

The Ghost calls my name, probably because of Asha’s abrupt arrival in front of him, but I am intent on my purpose. My feet grow swifter and more sure on the spiral steps.

I find Balekin’s cell is empty, the bars bent and broken, his opulent rugs wet and covered in sand.

Orlagh took Balekin. Stole a prince of Faerie from right under my nose.

I curse my own shortsightedness. I knew they were meeting, knew they were scheming together, but I was sure, because of Nicasia, that Orlagh truly wanted Cardan to be the bridegroom of the sea. It didn’t occur to me that Orlagh would act before hearing an answer. And I didn’t think that when she threatened to take blood, she meant Balekin.

Balekin. It would be difficult to get the crown of Faerie on his head without Oak putting it there. But should Cardan ever abdicate, that would mean a period of instability, another coronation, another chance for Balekin to rule.

I think of Oak, who is not ready for any of this. I think of Cardan, who must be persuaded to pledge himself to me again, especially now.

I am still swearing when I hear a wave strike the rocks, hard enough to reverberate through the Tower. The Ghost shouts my name again, from closer by than I expect.

I turn as he steps into view on the other side of the room. Beside him are three of the sea Folk, watching me with pale eyes. It takes me a moment to put the image together, to realize the Ghost is not restrained nor even menaced. To realize this is a betrayal.
