Shadow Creek

From New York Times bestselling author Joy Fielding-a chilling psychological thriller that explores the depths of psychopathic behaviour and the lengths to which a mother will go to protect her daughter. Due to a last-minute change in plans, a group of unlikely traveling companions finds themselves on a camping trip in the Adirondacks. They include the soon-to-be-divorced Valerie; her oddball friends, Melissa and James; her moody teenage daughter, Brianne; and Val's estranged husband's fiancée, Jennifer.
Val is dealing with unresolved feelings toward her ex and grappling with jealousy and resentment toward his younger, prettier new flame, a woman with some serious issues of her own. Brianne is sixteen and openly rebellious, caught up in a web of secrets and lies. What Val and her companions don't know is that a pair of crazed killers is wreaking havoc in the very same woods. When an elderly couple is found slaughtered and Brianne goes missing, Val finds herself in a nightmare much worse than anything she could have anticipated.
She was half-expecting it to be the trip from hell, but what she never could have predicted was that this impromptu little excursion would become an all-out struggle for survival.
