内容简介：
When a 1988 Hailey High class ring is found in the stomach of an unidentified murdered victim, NYPD Detective Rosemary Cooper travels to the small town, located on the Saint Lawrence River, to investigate. She not only identifies the John Doe, but is propelled from 2008 into the town's sinister past. A past where the Andrew sisters sing, Don't Sit Under The Apple Tree, and glaring headlines in Hailey's Comment proclaim: GERMAN U-BOAT SPOTTED IN OUR BACK YARD. Since neither she nor the man she seeks were born at the time of World War II, Coop is baffled as to why the predestination causality loop has zapped her to this time, this place. That is until she overhears the locals discuss patrolling the river, and "taking care of" the Krauts living among them. Most vocal is the town founder, Tobias Hailey, and a young Frank Cooper-who one day will become her father. Has she traveled back in time to interfere in the townspeople's plan to "take care of" the Krauts, thus paving the way for her father to fulfill his destiny as a U. S. congressman? Or is there a more ominous reason for her sojourn into the past?
