Eve Lattimore's family is like every other on their suburban street, with one exception. Her son Tyler has a rare medical condition that makes him fatally sensitive to light, which means heavy curtains and deadlocked doors protect him during the day and he can never leave the house except at night. For Eve, only constant vigilance stands between an increasingly restless teenage son and the dangers of the outside world. Until the night the unthinkable happens. When tragedy strikes, it becomes clear that this family is not the only one on the quiet cul-de-sac that is more complicated than it appears. And as Eve is forced to shield her family from harm, there are some crises she cannot control -- and some secrets that not even love can conceal.
