A girl who knows how you die. Her banshee roommate who knows when it happens. And wishes that sometimes, maybe, come true. . . .

Rosemary Thorpe has always been a bit different. She has the uncanny and unfortunate ability to foresee people's deaths, which tends to land her in hot water. Well, not actual hot water--where it lands her is a place between worlds called Fern's School for Wayward Fae, where Rosemary learns that her powers come from being part fae.

At Fern's School, Rosemary meets others who are part fae--including Trym, her banshee roommate whose screams can kill, and Essie, a djinn who grants wishes. But just as Rosemary settles in, a student vanishes in thin air. And it's up to all the kids to use their curious gifts to find their missing friend. . . .
