Jazinta (Jaz) Wallis can see into a parallel world of darkness, writhing with demon activity. As an outsider to her world, with purple-streaked hair and a quirky dress sense, she’s mercilessly harassed at school, especially by Kacey Matthews, the sinister school bully.

Even Brandon Kelly - Jaz’s logical, strong, and good-looking lifelong friend - has trouble believing Jaz and the reality she faces, despite experiencing ‘hallucinations of fiendish creatures trying to kill him and voices that whisper he’s no good.

Can the two friends work together with their powerful angel guardians to defeat the demon overlord and set the city free?
