When a girl with a troubled history of finding dead bodies investigates the murder of her ex, she uncovers a plot to put herself—and everyone she loves—on the list of who's next.   Flora Calhoun has a reputation for sticking her nose where it doesn't belong. After stumbling upon a classmate's body years ago, the trauma of that discovery and the police's failure to find the killer has haunted her ever since. One night, she gets a midnight text from Ava McQueen, the beautiful girl who had ignited Flora's heart last summer, then never spoke to her again.   Just in time to witness Ava's death from a gunshot wound, Flora is set on a path of rage and vengeance for all the dead girls whose killer is never found. Her tunnel-visioned sleuthing leads to valuable clues about a shocking conspiracy involving her school and beyond, but also earns her sinister threats from the murderer. She has a choice: give up the hunt for answers, or keep digging and risk her loved ones' lives. Either way, Flora will regret the consequences. Who's next on the killer's list?
