“Shadowclaw, Shadowclaw, come and play!” Those were the words Ethan and his friends chanted as children during a slumber party séance to summon a legendary ghoul. It was the night his best friend, Robby, ended up murdered. Years later, Ethan is an anxious and superstitious teenager doing his best to forget the past and convince himself that Shadowclaw was only a story. But when he finds himself transported back in time to that fateful night, he realizes he actually has a chance to change the past and save Robby from a horrific death. It also means he’ll have to face a supernatural entity he’s always told himself was just a legend that couldn’t hurt him: Shadowclaw.
