Night School: Fracture - Number 3 in series

Cimmeria has been more than a school for Allie, it''s been a safe haven. But no longer.
A nefarious group - one that is tied up with Allie''s family in ways she could barely imagine - is trying to destroy everything Cimmeria stands for.
Even worse, it''s clear that somebody 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 an attack from outside they need to worry about . . .
