As Rosie Connors starts her second year at King's Preparatory, she is finding the place she calls home less than pleasant. Especially as she notices her magic isn't quite within her grasp. Unfortunately, she isn't alone. Other students, and even teachers, are also losing their gifts, and Rosie has a feeling two mysterious newcomers are behind it.

When no one believes her suspicions, she searches not just for proof, but a solution to restore everyone's power. Meanwhile, pandemonium ensues as supernatural creatures attack each other around every corner, making her school a deadly battle arena.

Can she stop the fighting, possibly killing, before it is too late and the school is shut down?
