Sinners and Saints : Forensic nurse Chastity O'Connor is trying to put the past behind her. After exposing her father as the monster he was, she was shunned by her family. But now, one of them needs her help: her brother-in-law Max Stanton, whom she has never met. Chastity's sister, Faith, is missing from the doctor's upscale home in New Orleans, and Max needs Chastity's help. To find her missing sister, she has to dredge up her own ghosts in a city where forensics are an old boys club and a woman can find trouble in her sleep. As a hurricane threatens the sea-level city, Chastity must search in increasing desperation for a sister who seems to be in terrible trouble.
