Sadie Rockwood and Julia Alessi are best friends, both eighteen and finishing up their senior year of high school. They are inseparable and have been for quite some time. Sadie has always yearned for a sense of belonging and unconditional love, something her alcoholic mother could never provide. Julia's family, however, seems to offer just that. But when she especially finds solace and acceptance in Julia's father, an unintentional attraction forms. As the two bond in secrecy, Sadie's issues worsen, and navigating through them with the unavailable man causes a destructive downward spiral that pulls him and the unsuspecting family along for the ride.
