Fifteen-year-old Kate Christenson is pretty sure she's about to experience the worst possible summer at her grandparents' rural farm in Baudette, Minnesota. Without cable, cell phones, or computers, she is headed for total isolation and six tedious weeks of boredom. Until the storm. A freak lightning accident has Kate waking up in 1960. But she is not herself. She's the aunt she never met but has eerily resembled her entire life. Thrust into living a dirt-poor, rural farm existence, Kate struggles to make sense of her situation - a boyfriend with a dark side, a "townie" who steals her heart, and the knowledge that 1960 is the very summer her aunt drowns in the local river. But was the drowning an accident or a suicide... or something much worse?

“There never was a body, you know.” Such is the bizarre statement from Gran only weeks after Kate has returned from an accidental time traveling incident, surviving certain death…twice. Capturing Sarah’s killer seemed to be the reason for Kate’s disappearance, but Gran believes otherwise. Learning of Kate’s power to time travel loosens memories and desires Gran has long since buried. Gran is set on finding Sarah, who she believes never died the night she was thrown in the river, but instead, went back in time through the Rapid River portal. With rudimentary research and analysis, Gran thinks she has unlocked the secrets to controlling the time traveling link that she and Kate share with their ancestors and she wants to use Kate to bring Sarah back. When Kate agrees, she is shocked to learn that in this more aggressive form of time travel she doesn’t become Sarah, but trades places with her: Kate is sent to Baudette, Minnesota in 1910 while Sarah travels to 2000! Baudette’s catastrophic 1910 fire and the typhoid epidemic are the least of Kate’s worries. Her chances of a return trip are thwarted with the struggle just to survive, and Sarah, reliving her lost childhood in the comforts of the modern day, decides she’ll never return to the past...
