There are no teachers, no holidays, and no friendships, save strategic ones. Survival is more important than any letter grade, for the school won’t allow its students to leave until they graduate… or die! The rules are deceptively simple: Don’t walk the halls alone. And beware of the monsters who lurk everywhere. El is uniquely prepared for the school’s dangers.

The problem? Her powerful dark magic might also kill all the other students.

But then there are the “Sleep Songs.” A woman’s hauntingly beautiful voice sings a ballad that is anything but soothing—it’s disturbing, really, more of a warning than a relaxation—but it works.

Because while he might not have any memory of it, he’s one of twenty people who have heard this sinister song before and the only one who is still alive.
