Redline — Lisa Nowak

Now that Jess DeLand has escaped her alcoholic mother's grip, all she wants is a chance to be normal. To hang out with her wisecracking-but-intuitive boyfriend Cody, learn as much she can about restoring cars from her mentor Kasey, and fill in as substitute big sister to Rhett when her friend Teri Sue goes off to college. But when her past crashes headlong into her present, all hopes of normal go spinning off into the weeds. Jess's attempts to spare her friends--and herself--from the things she'd rather keep hidden, threaten to destroy the new life she's built. Maybe normal is too much to ask for.
