New girl Sadie just wants to stay out of trouble and blend in. When she learns she has the fiercest animal light of all, she is invited to join the group of it girls known as the Pack, led by Lindsey, the school’s queen of the jungle. Soon Sadie is consumed by social drama and her secret feelings for an off-limits private-school boy. 

Charm House is supposed to protect them, but danger looms when someone starts to threaten the girls. Is the school in jeopardy—or is someone trying to tear the Pack apart?
