The Nowhere Girls by Amy Reed
Grace is new in Prescott and plans to stay under the radar, but when she discovers the former occupant of her room, Lucy, was run out of town after accusing several (popular) boys at school of rape she’s finding it hard to stay quiet.
Rosina and Erin are the token freaks of school. Rosina is bogged down by responsibilities and expectations from her family and dealing with her crush on a cute cheerleader. Erin has Asperger’s and is trying to compartmentalize her own past traumatic events.
