Every changeling is different. Some, like me, are relatively weak. Others get a full measure of faerie magic—sometimes more than their pureblood parents—and they can’t handle it. Those are the ones that get whispered about in the pureblood Courts, the ones no one names once the fires have been extinguished and the damages have been tallied. I learned the stories when I was little, first from Mom as she tucked me into bed, and later, after things changed, from the ones who came to get me. I don’t know who was more relieved when we found out how weak my powers are—my mother or me.

Even weak changelings can be dangerous. They’re allowed to stay with their human parents while they’re young enough to keep their masks up instinctively, but that early control fades as they get older, and choices must be made. Some changelings have to make the Changeling’s Choice as early as three; others hold out until their late teens. That was the only time in my life that I’ve been on the precocious end of the curve, because I was seven years old when my baby magic started to fail.

I don’t know how they knew, and I don’t know how they found us. I was in my room conducting a tea party for my stuffed animals, and they were suddenly there, stepping through a hole in my wall, beautiful and terrible and impossible to turn away from. Looking at them was like looking into the sun, but I did it anyway, until I thought I would go blind from looking.

One of them—a man with hair the color of fox fur and a long, friendly face—knelt in front of me, taking my hands. “Hello there,” he said. “My name is Sylvester Torquill. I’m an old friend of your mother’s.”

“Hello,” I said, as politely as I could through a mouthful of awe. “I’m October.”

He laughed, unsteadily, and said, “October, is it? Well, October, I have a question for you. It’s a very important question, so I need you to think hard before you answer. Can you do that for me?”

“I can try,” I said, frowning. “Will you tell me if I answer wrong?”

“There are no wrong answers, October. Only right ones.” The door—the real door—opened, and my mother stepped into the room. She froze when she saw Sylvester kneeling in front of me, holding my hands, but she didn’t say a word. Tears started rolling down her cheeks. I’d never seen her cry before.

“Mommy!” I shouted, trying to pull my hands free, to run to her and stop those tears.

Sylvester tightened his grip. “October.” I kept tugging. “October, look at me. You can go to your mother when you answer me.” Sniffling and sullen, I stopped pulling and turned to face him. “Good girl. Now. Are you a human girl, October? Or are you fae?”
