Sixteen-year-old Allie isn't like other girls. Instead of spending her summer break sitting around on the beach, she takes the epic vacation of a lifetime. Tornado chasing. And she's not disappointed. Just a few miles from the town of Evansburg, Nebraska, Allie meets her dream of seeing a tornado. In person. She can't wait to tell her friends back home. Never mind that her parents are going to kill her. But her dream soon turns into a nightmare, and a strange event leaves her shocked. Confused. When she returns home to Wisconsin, something's...different. Allie now bears a curse so awful, it could destroy everyone and everything she's ever known. With her best friend, Tommy, Allie must return to the plains to find a way to reverse it. She enters a world that she had never imagined, where she becomes a pawn in a fight to save the people of Evansburg from her fate...or to destroy them.
