When word of a murdered teen sweeps through the tight-knit community, fear quickly wipes away their illusion of safety. Then comes the official report... A young girl, Sophie Peters, has been found dead in the woods. Her death was supposedly caused by an accidental overdose—or maybe suicide. Deep down, Casey knows—Sophie's death was not an accident. Besides the fact they look like long-lost twins, Sophie once saved Casey's life, and now Casey is determined to repay her by bringing her killer to justice. The search for the town’s first murderer is on, leading Casey down a road of lies and deceit. The people she thought she knew aren't at all who they seem… As she digs deeper into the case, Sophie's older brother, Mason, becomes determined to help find his sister's killer. He won't rest until they stop the monster responsible for leaving his only sibling to die in the woods. Mason would like to call it justice, but in reality, it’s more like a hell-bent mission for revenge. Can Casey and Mason work together to find the killer, or will the secrets of the town, the murder, and even Sophie herself tear them apart? less

It's the anniversary of Sophie Peter's death, and Casey and Mason are still stuck in the past. Events from the year before still haunt their every waking moment, and even with the murderer behind bars, they can't seem to move on. When the body of one of their classmates turns up on the outskirts of the woods, not far from the spot that Sophie's body was found in, Casey and Mason can't help but to think that the murders are connected in some way... moreIt's the anniversary of Sophie Peter's death, and Casey and Mason are still stuck in the past. Events from the year before still haunt their every waking moment, and even with the murderer behind bars, they can't seem to move on. When the body of one of their classmates turns up on the outskirts of the woods, not far from the spot that Sophie's body was found in, Casey and Mason can't help but to think that the murders are connected in some way. Tiffany Hawkins fits the description of Sophie perfectly. They both died at the same age, have the same shade of blonde hair and green eyes, and even have similar physiques. Finally, when Tiffany was found, she had the same arrow mark cut into the inside of her right wrist that Sophie had on hers when her body was found, and that Casey now has. Suddenly Casey and Mason are thrown back into a world of lies and deceit, trying to find out the truth about the horrific event that took his sister's life exactly a year ago. Is the killer still among them, or is a sadistic copy cat on the loose? Last year, Casey barely escaped with her life, but will she be so lucky this time around? less
