Cold Summer by Gwen Cole starts off with Kale sitting in his yard thinking about how his life has changed. The mystery of this change pulled me into the story. Harper is moving into her Uncle Jasper’s home where she’s spent her summers when she was younger. She’s looking forward to seeing the neighbors, Kale and his family. The alternating points of view between Kale and Harper tell their stories, bits at a time. Kale struggles with daily life and responsibilities because he gets pulled out of the present and travels to the past. He feels like he has absolutely no control over his life and he’s been kicked off the baseball team and expelled from school, slowly losing everything he cares about. He has been traveling into a World War II war zone and it’s happening more often. Harper helps Kale deal with the time traveling and gives him something to be happy about. This book is genre bending since it’s historical fiction (World War II), science fiction (time travel), contemporary and romance all in one; 4 stars.
