Johnson, Maureen. 2006. Devilish.
Jane Jarvis and Allison Concord are two girls who just don't belong in the social hierarchy of Saint Teresa's Preparatory School for Girls. Jane with her spiked blond hair doesn't care. She's her own person and would rather make fun of A3 (Elsie Fast, Tracey Pils, and Lai Barden) than be one of the ever-so-shallow popular girls. Allison, on the other hand, would give anything, risk everything, to be with the in crowd. Unfortunately for her, there's a new girl in town who knows her weakness. Enter onto the scene the mysterious Lanalee who appears just in time to 'save' Allison from dealing with the repercussions of her greatest humiliation--throwing up in front of the entire school at an assembly. Overnight, Allison is transformed into everything she's ever wanted to be...popular, trendy, with beautiful hair and stylish clothes to support her new rise to the top. But more than just the outward appearance is changing, Jane barely recognizes her friend. Can Jane solve the mystery of her friend's strange behavior? And what exactly did Allison bargain with? Is being popular worth paying any price?
Devilish isn't a novel for everyone. But if you're looking for a novel set at a Catholic school where demons and demon hunters battle it out to win human souls (to clarify demons want possession of a soul and demon hunters want to protect humans from such a fate) then this could be the perfect novel for you. Set in Rhode Island, Devilish is an interesting twist to your typical high school drama.
