Plum by Andy Anderegg

For fans of Sarah Rose Etter and Scott McClanahan, Plum is a darkly beautiful, unflinching novel about modern girlhood in the internet age, the daily toll of trauma, and the limits of love.
Told entirely in the second person, Plum follows J as she grows from kid to teen in a house ruled by her alcoholic dad and complicit mother. Her older brother is sometimes wonderful, sometimes gross, and he's her only hope of getting out. J's world is one of nail polish, above-ground pools, and drive-thrus-and of violence, carelessness, and so many rules. J covets the peace that comes when she slips on her headphones, turns on her handheld radio, and dreams of how she and her brother can make their escape.
When her brother leaves home and disappears, so does J's best chance to flee her parents' chaotic orbit. Alone and angry, J reaches through her computer screen for the life she wants: blonde hair, glittering nails, attention, freedom. As she stumbles into adulthood with no template to follow, J must figure out how to build a family for herself full of the love she deserves. In her brutally compelling debut, Anderegg turns her singular gaze on the generational patterns of addiction and abuse.
