Very Good Girls - Naomi Foner Gyllenhaal

The summer before college presents two best friends, Lilly and Gerri, with the opportunity to shed their good girl images. Both girls want to lose their virginity and explore another side of who they are. But their dark and different home lives and the introduction of two bad boys, threaten to destroy their friendship without it being the nice coming-of-age summer that the two girls envisioned.
