Mosh Pit by Kristyn Dunnion
It's about a punk rawk girl named Simone who is an open lesbian, in love with her bisexual friend Cherry. It's her struggles with growing up, family, love, and the subculture.
It is my all time favorite book.
Hello Groin by Beth Groobie
An average girl struggling with her sexuality and coming to terms with her love for a friend while coming out to her parents and her school, and her boyfriend.
FOXFIRE: Confessions of a Girl Gang by Joyce Carol Oates
a story set in the 1950's following a girl named Maddy. A wandered named Legs Sadovsky comes to her small town and starts a female gang bound on pushing back at the men. Legs is not openly gay but the book has some various undertones, along with feminism.
The movie wasn't half bad, it had Angelina Jolie in it and a rather nice topless scene.
