Despite a lifetime of breaking the rules, twelve-year-old Issa Igwe never expected to land in witch prison. At least that’s what she calls The Siren School outside of its hallowed halls. It’s actually the country’s most prestigious boarding school for magically gifted girls, and Issa’s parents insist that she attend . . . even though the school’s creepy history is the stuff of legend. When a devastating loss overturns Issa’s world, Issa decides to break one of her new school’s biggest rules of all: she’s going to use bitter magic to turn back time. To succeed, she must snatch sleep-inducing feathers from the backs of magical creatures, sneak out while avoiding the Night Children—whoever they are—and even raise the dead. Her nighttime explorations bring the school’s darkest secrets to light, and reveal a new power within Issa herself. It turns out that a rule-breaker might be just what The Siren School needs to undo an ancient evil . . .
