“I—I want to be your knight,” I stammer.

His eyebrows go up. “Unexpected,” he says. “And pleasing. What else?”

“I don’t understand.” I twist my hands together so he can’t see how they are shaking.

“Desire is an odd thing. As soon as it’s sated, it transmutes. If we receive golden thread, we desire the golden needle. And so, Jude Duarte, I am asking you what you would want next if I made you part of my company.”

“To serve you,” I say, still confused. “To pledge my sword to the crown.”

He waves off my answer. “No, tell me what you want. Ask me for something. Something you’ve never asked from anyone.”

Make me no longer mortal, I think, and then am horrified at myself. I don’t want to want that, especially because there is no way to get it. I will never be one of the Folk.

I take a deep breath. If I could ask him for any boon, what would it be? I understand the danger, of course. Once I tell him, he is going to try to strike a bargain, and faerie bargains seldom favor the mortal. But the potential for power dangles before me.

My thoughts go to the necklace at my throat, the sting of my own palm against my cheek, the sound of Oak’s laughter.

I think of Cardan: See what we can do with a few words? We can enchant you to run around on all fours, barking like a dog. We can curse you to wither away for want of a song you’ll never hear again or a kind word from my lips.

“To resist enchantment,” I say, trying to will myself to stillness. Trying not to fidget. I want to seem like a serious person who makes serious bargains.

He regards me steadily. “You already have True Sight, given to you as a child. Surely you understand our ways. You know the charms. Salt our food and you destroy any ensorcellment on it. Turn your stockings inside out and you will never find yourself led astray. Keep your pockets full of dried rowan berries and your mind won’t be influenced.”

The last few days have shown me how woefully inadequate those protections are. “What happens when they turn out my pockets? What happens when they rip my stockings? What happens when they scatter my salt in the dirt?”

He regards me thoughtfully. “Come closer, child,” he says.

I hesitate. From all I have observed of Prince Dain, he has always seemed like a creature of honor. But what I have observed is painfully little.

“Come now, if you are going to serve me, you must trust me.” He is leaning forward in the chair. I notice the small horns just above his brow, parting his hair on either side of his regal face. I notice the strength in his arms and the signet ring gleaming on one long-fingered hand, carved with the symbol of the Greenbriar line.

I slide from the chair arm and walk over to where he sits. I force myself to speak. “I didn’t mean to be disrespectful.”

He touches a bruise on my cheek, one I hadn’t realized was there. I flinch, but I don’t move away from him. “Cardan is a spoiled child. It is well-known in the Court that he squanders his lineage on drink and petty squabbles. No, don’t bother to object.”

I don’t. I wonder how it was that Gnarbone came to tell me only that a prince was waiting for me downstairs, but not which prince. I wonder if Dain told him to give me that specific message. A well-seasoned strategist waits for the right opportunity.

“Although we are brothers, we are very different from each other. I will never be cruel to you for the sake of delighting in it. If you swear yourself into my service, you will find yourself rewarded. But what I want you for is not knighthood.”

My heart sinks. It was too much to believe that a prince of Faerie had dropped by to make all my dreams come true, but it was nice while it lasted. “Then what do you want?”

“Nothing you haven’t already offered. You wanted to give me your oath and your sword. I accept. I need someone who can lie, someone with ambition. Spy for me. Join my Court of Shadows. I can make you powerful beyond what you might ever hope. It’s not easy for humans to be here with us. But I could make it easier for you.”

I allow myself to sink into a chair. It feels a little bit like expecting a proposal of marriage, only to get offered the role of mistress.

A spy. A sneak. A liar and a thief. Of course that’s what he thinks of me, of mortals. Of course that’s what he thinks I am good for.

I consider the spies I have seen, like the parsnip-nosed and hunched figure Madoc consults with sometimes, or a shadowy, gray-shrouded figure whose face I’ve never managed to spot. All the royals probably have them, but doubtless part of their skill is in how well hidden they are.

And I would be well hidden, indeed, hidden in plain sight.

“It is perhaps not the future you imagined for yourself,” Prince Dain says. “No shining armor or riding into battle, but I promise you that once I am the High King, if you serve well, you will be able to do as you like, for who can gainsay the High King? And I will put a geas on you, a geas of protection from enchantment.”

I go very still. Usually given to mortals in exchange for their service, geases grant power, with a kick-in-the-teeth exception that comes upon you when you least expect it. Like, you’re invulnerable, except to an arrow made of the heartwood of a hawthorn tree, which just so happens to be the exact kind of arrow that your worst enemy favors. Or you’ll win every battle you’re in, but you’re not allowed to refuse invitations to dinner, so if someone invites you to dinner right before a battle, you’re not going to be able to show up for that fight. Basically, like everything about Faerie, geases are awesome, and also they suck. Yet, it seems like that’s what I am being offered.

“A geas,” I echo.

His smile widens, and after a moment, I know why. I haven’t said no. Which means I am thinking of saying yes.

“No geas can save you from the effects of our fruits and poisons. Think carefully. I could grant you the power to enrapture all who looked upon you instead. I could give you a spot right there.” He touches my forehead. “And anyone who saw it would be struck with love. I could give you a magical blade that cuts through starlight.”

“I don’t want to be controlled,” I say, my voice a whisper. I can’t believe I am saying this out loud, to him. I can’t believe I am doing this. “Magically, I mean. Give me that, and I will manage the rest.”

He nods once. “So you accept.”

It’s frightening to have a choice like this in front of me, a choice that changes all future choices.

I want power so badly. And this is an opportunity for it, a terrifying and slightly insulting opportunity. But also an intriguing one. Would I have made a good knight? I have no way of knowing.

Maybe I would have hated it. Maybe it would have meant standing around in armor and going on dull quests. Maybe it would have meant fighting people I liked.

I nod and hope I make a good spy.

Prince Dain rises and touches my shoulder. I feel the shock of the contact, like a spark of static. “Jude Duarte, daughter of clay, from this day forward no Faerie glamour will addle your mind. No enchantment will move your body against your will. None save for that of the maker of this geas.

“Now no one will be able to control you,” he says, and then pauses for a moment. “Except for me.”

I suck in a breath. Of course there’s a sting in the tail of this bargain. I cannot even be angry with him; I should have guessed.
