In addition to his duties as the school tailor, Kade was an amateur historian and mapmaker rolled into one, recording the stories of all the children who came through the school. He said it was because he was trying to accurately map the Compass that defined Nonsense and Logic, Virtue and Wickedness, all of the other cardinal directions of the worlds on the other side of their doors. Cora thought that was probably true, but she also thought he liked the excuse to talk to people about their shared differences, which became their shared similarities when held up to the right light. They had all survived something. The fact that they had survived different somethings didn’t change the fact that they would always be, in certain ways, the same.

“Can it be put back?”

Christopher shook his head, and muttered weakly, “Wouldn’t want it. There was something wrong inside. A dark thing. The doctors said it was a tumor. But the Skeleton Girl piped it away and freed me. Owe her … everything.”

“But…”

“It’s still mine.” There was a flicker of fierceness in Christopher’s voice, there and gone in an instant, like it had never existed in the first place.

Kade sighed, patting Christopher on the shoulder before he rose and walked over to stand next to Cora at the window. Dropping his voice to a low murmur, he said, “This doesn’t happen as much as it used to—I guess the universe figured out it was an asshole move—but it’s happened before. Kids who went through doors and came back with some magical item or other that still worked in our world, where there isn’t supposed to be much magic at all.”

“So?”

“So you want magic in our world, you pretty much have to be paying for it out of your own self, somehow. Most of the time, the magic item’d been tied to the person with blood or with tears or with something else that came out of their bodies. Or, in this case, a whole damn bone. The magic that powers the flute is Christopher. If he doesn’t get it back…”

Cora turned to gape at him, horrified. “Are you saying he’ll die?”

“Maybe not die. He’s never been separated from it for more than a few minutes. Maybe he’ll just get really sick. Or maybe the cancer will come back. I don’t know.” Kade looked frustrated. “I interview all the newbies, I write everything down, because there are so many doors, and so many little variations on the theme, and we don’t know. He might die if we don’t get it back. He wouldn’t be the first.”
