Amnesia: Naked in the Winter Wind — Dani Haviland

A plump and perky 21st century Alaskan lady visits North Carolina and winds up in the late 18th century with a rejuvenated body, but without a memory. She braves a drunken mob to rescue a mountain man who claims her as his wife and calls her Evie. Then the excitement begins. Kidnappings, caves, and cougars prove to be a challenge for the tough old lady living in a teenager's foxy body. Using nothing but her wit and wisdom - give or take a knife or two - she survives, but winds up in an unexpected situation that her husband can't, or won't, accept.
