Ten years. If we could keep Oak out of Faerie for ten years, he could grow into the person he’s going to be.

Of course, by then, he might have to fight to get his throne back. Someone—probably Madoc, possibly Balekin, maybe even one of the other minor kings or queens—could squat there like a spider, consolidating power.

I squint at the black water. If only there were a way to keep the throne unoccupied for long enough that Oak becomes his own person, without Madoc making war, without any regent at all.

I stand up, having made my decision. For good or ill, I know what I am going to do. I have my plan. Madoc would not approve of this strategy. It’s not the kind he likes, where there are multiple ways to win. It’s the kind where there’s only one way, and it’s kind of a long shot.

As I stand, I catch my own reflection in the water. I look again and realize that it can’t be me. The Lake of Masks never shows you your own face. I creep closer. The full moon is bright in the sky, bright enough to show me my mother looking back at me. She’s younger than I remember her. And she’s laughing, calling over someone I cannot see.

Through time, she points at me. When she speaks, I can read her lips. Look! A human girl. She appears delighted.

Then Madoc’s reflection joins hers, his hand going around her waist. He looks no younger then, but there is an openness in his face that I have never seen. He waves to me.

I am a stranger to them.

Run! I want to shout. But, of course, that’s the one thing I don’t need to tell her to do.

The Bomb looks up when I enter. She’s sitting at the wooden table, measuring out a grayish powder. Beside her are several spun glass globes, corked shut. Her magnificent white hair is tied up with what looks like a piece of dirty string. A smear of grime streaks over her nose.

“The rest of them are in the back,” she says. “With the princeling, getting some sleep.”

I sit down at the table with a sigh. I’d been tensed up to explain myself, and now all that energy has nowhere to go. “Is there anything around to eat?”

She gives me a quick grin as she fills another globe and sets it gingerly in a basket by her feet. “The Ghost picked up some black bread and butter. We ate the sausages, and the wine’s gone, but there might still be some cheese.”

I rummage through the cupboard, take out the food, and then eat it mechanically. I pour myself a cup of bracing and bitter fennel tea. It makes me feel a little steadier. I watch her make explosives for a while. As she works, she whistles a little, off-key. It’s odd to hear; most of the Folk are musically gifted, but I like her tune better for being imperfect. It seems happier, easier, less haunting.

“Where will you go when all this is done?” I ask her.

She glances over at me, puzzled. “What makes you think I’m going anywhere?”

I frown at my nearly empty cup of tea. “Because Dain’s gone. I mean, isn’t that what the Ghost and the Roach are going to do? Aren’t you going with them?”

The Bomb shrugs her narrow shoulders and points a bare toe at the basket of globes. “See all these?”

I nod.

“They don’t travel well,” she says. “I’m going to stay here, with you. You’ve got a plan, right?”

I am too flummoxed to know what to say. I open my mouth and begin to stammer. She laughs. “Cardan said that you did. That if you were just making a trade, you would have done it already. And if you were going to betray us, you’d have done that by now, too.”

“But, um,” I say, and then lose my train of thought. Something about how he wasn’t supposed to be paying that much attention. “What do the others think?”

She goes back to filling globes. “They didn’t say, but none of us likes Balekin. If you’ve got a plan, well, good for you. But if you want us on your side, maybe you could be a little less cagey about it.”

I take a deep breath and decide that if I am really going to do this, I could use some help. “What do you think about stealing a crown? Right in front of the kings and queens of Faerie?”

Her grin curls up at the corners. “Just tell me what I get to blow up.”

Twenty minutes later, I light the stub of a candle and make my way to the room with the cots. As the Bomb said, Cardan is stretched out on one, looking sickeningly handsome. He’s washed his face and taken off his jacket, which he has folded up under his head for a pillow. I poke him in the arm, and he comes awake instantly, raising his hand as though to ward me off.

“Shhhh,” I whisper. “Don’t wake the others. I need to talk to you.”

“Go away. You told me you wouldn’t kill me if I answered your questions, and I did.” He doesn’t sound like the boy who kissed me, sick with desire, just hours ago. He sounds sleepy, arrogant, and annoyed.

“I am going to offer you something better than your life,” I say. “Now, come on.”

He stands, shouldering on his jacket, and then follows me into Dain’s office. Once we’re there, he leans against the doorjamb. His eyes are heavy-lidded, his hair messy from the bed. Just looking at him makes me feel hot with shame. “You sure you brought me here just to talk?”

It turns out that having kissed someone, the possibility of kissing hangs over everything, no matter how terrible an idea it was the first time. The memory of his mouth on mine shimmers in the air between us. “I brought you here to make a deal with you.”

His eyebrow goes up. “Intriguing.”

“What if you didn’t have to go hide somewhere in the countryside? What if there were an alternative to Balekin’s being on the throne?” That’s clearly not what he was expecting me to say. For a moment, his insouciant swagger fails him.

“There is,” he says slowly. “Me. Except I would be a terrible king, and I would hate it. Besides, Balekin is unlikely to put the crown on my head. He and I have never gotten on particularly well.”

“I thought you lived in his house.” I cross my arms over my chest protectively, trying to push away the image of Balekin punishing Cardan. I can’t have any sympathy now.

He tips his head back, looking at me through dark lashes. “Maybe living together is the reason we don’t get on.”

“I don’t like you, either,” I remind him.

“So you’ve said.” He gives me a lazy grin. “So if it’s not me and it’s not Balekin, then who?”

“My brother, Oak,” I tell him. “I’m not going to go into how, but he’s of the right bloodline. Your bloodline. He can wear the crown.”

Cardan frowns. “You’re sure?”

I nod. I don’t like telling him this before I ask him to do what I need, but there’s little he can do with the knowledge. I will never trade him to Balekin. There is no one to tell but Madoc, and he already knows.

“So Madoc will be regent,” Cardan says.

I shake my head. “That’s why I need your help. I want you to crown Oak the High King, and then I’m going to send him to the mortal world. Let him have a chance to be a kid. Let him have a chance at being a good king someday.”

“Oak might make different choices than the ones you want him to,” Cardan says. “He might, for instance, prefer Madoc to you.”

“I have been a stolen child,” I tell him. “I grew up in a foreign land for a far lonelier and worse reason than this. Vivi will care for him. And if you agree to my plan, I’ll get you everything you asked for and more. But I need something from you—an oath. I want you to swear yourself into my service.”

He barks out the same surprised laugh he made when I threw my knife at the desk. “You want me to put myself in your power? Voluntarily?”

“You don’t think I’m serious, but I am. I couldn’t be more serious.” Inside my crossed arms, I pinch my own skin to prevent any twitches, any tells. I need to seem completely composed, completely confident. My heart is speeding. I feel the way I did when I was a child, playing chess with Madoc—I would see the winning moves ahead of me, forget to be cautious, and then be brought up short by a move of his I hadn’t predicted. I remind myself to breathe, to concentrate.

“Our interests align,” he says. “What do you need my oath for?”

I take a deep breath. “I need to be sure you won’t betray me. You’re too dangerous with the crown in your hands. What if you put it on your brother’s head after all? What if you want it for yourself?”

He seems to think that over. “I’ll tell you exactly what I want—the estates where I live. I want them given to me with everything and everyone in them. Hollow Hall. I want it.”

I nod. “Done.”

“I want every last bottle in the royal cellars, no matter how old or rare.”

“They will be yours,” I say.

“I want the Roach to teach me how to steal,” he says.

Surprised, I don’t answer for a moment. Is he joking? He doesn’t seem to be. “Why?” I ask finally.

“It could come in useful,” he says. “Besides, I like him.”

“Fine,” I say incredulously. “I will find a way to work it out.”

“You really think you can promise all that?” He gives me a considering look.

“I can. I do. And I promise we will thwart Balekin. We will get the crown of Faerie,” I tell him heedlessly. How many promises can I make before I find myself accountable for them? A few more, I hope.

Cardan throws himself into Dain’s chair. From behind the desk, he gazes at me coolly from that position of authority. Something in my gut twists, but I ignore it. I can do this. I can do this. I hold my breath.

“You can have my service for a year and a day,” he says.

“That’s not long enough,” I insist. “I can’t—”

He snorts. “I am sure that your brother will be crowned and gone by then. Or we will have lost, despite your promises, and it won’t matter anyway. You won’t get a better offer from me, especially not if you threaten me again.”
