A riveting story of loyalty, betrayal and survival by a New York Times bestselling author. It is the summer of 2000, and Bell, a student from Minnesota, is employed at an exclusive restaurant on Mackinac Island. With a circumference of just nine miles and no automobiles allowed, this unique resort on Lake Michigan is teeming with horse-drawn carriages, topshelf vodka, bicycles, smoked whitefish and wild, inspiring relationships. Forty years later, Bell is stranded in her St. Paul home clearing away the belongings of a lifetime while she awaits the arrival of a guest from that deceptively idyllic summer--a guest who may hold the key that can finally unlock the secrets of that long ago summer.
