Her voice was toneless, nothing in her expression telling me whether she considered Tristan’s absence a good or bad thing, or whether she cared at all. And before I could so much as blink, she had stepped into our world. Although stepped wasn’t the right word – one moment she was there and the next moment here. And while there she’d seemed as solid as Sabine or me, here she appeared like a mist that had coalesced into the shape of a woman, fluid, shifting, and changing. Her eyes met mine, and I swore they delved into the depths of my soul, flipping through my memories like pages of a book. Tristan had told me that the trolls’ magic had been corrupted by iron and mortality, that it was nothing like that of their immortal ancestors. But he’d never told me what they could do, and I was starting to fear what it would mean to find out.

“What is it you want, Princess?” The Queen’s voice was mocking, but that concerned me far less than my growing suspicion that she had plans for me. Plans that I wouldn’t like. That she’d ask me for something I didn’t want to give. But I’d come too far to come away with nothing.

“You can see anywhere you want?” I asked. “Anyone?”

“What will you give me for the answer?” The settee was coated with ice, but it gave beneath her as she settled as though it were stuffed with down.

I nibbled on my lip. “Nothing. I already know you can. What I want is to see… and hear what our enemy is up to. What they’re planning. Where they are now.”

She tapped a claw – no, a fingernail – against one tooth. “What will you give me in return?”

“What do you want?” I countered.

Her lips pursed, and she drifted one hand through the air as though conducting an orchestra. “A song.”

I blinked, more stunned by the odd request than I would have been if she’d asked for my life. “A song?”

She held up one finger. “Your favorite song.”

I glanced sideways at Sabine, who had been silent through the exchange thus far. Her back was pressed against the wall. Despite the chill, her cheeks were leached of color, the whites of her eyes gleaming in the lamplight. Without taking her gaze off the fairy, she shook her head.

I ground my teeth, and glanced back at the queen. Looking at her gave me a headache – I kept seeing one thing and then another, and I didn’t know what was real. “How is it even possible for me to give you a song?”

“Agree to the bargain. Sing the song. Then it will be mine.”
