Off Limits: How a Friend Saved My Life - Nitty Gritty series, #3

Lindsay looks and acts like the perfect fifteen year-old, but she's hiding a dirty little secret that no amount of fashionista coverings can make better. Telling her mother her step-father is molesting her is not an option. Trying to kill herself again haunts her more than the scars on her wrists, and pretending to be perfect at school might very well drive her over the edge. Megan knows all about lying.
It's been part of her life ever since she realized the only way to escape her poverty-stricken neighborhood was to work hard, keep her mouth shut and wear a mask no one can penetrate. All that changes when Lindsay befriends her. Can two girls who have little in common discover the value of a real friendship or will the secrets they dare not speak destroy them both?
