Cimmeria Academy has been more than a school for Allie, it's been a safe haven. But no longer.
The school - her friends, her teachers - are under attack. A nefarious group, a group that Allie and her mysterious family might have more to do with than she could've ever realized, is trying to destroy everything Cimmeria stands for.
And throughout it all, someone they eat with, sleep with, train with, is betraying them. There's a spy in Night School. As the paranoia grows and the fights begin, it's not the enemies outside they have to worry about.
They're hurting themselves.
