Стивен Стирлинг: Island in the Sea of Time

A cosmic disturbance transports the island of Nantucket and its inhabitants over three thousand years back in time to the shores of a Stone Age America. In addition to coping with the day-to-day problems of survival and the trauma of losing all connection with the modern world, the residents of the time-stranded island find their lives complicated by the presence of native tribes across the water. Stirling s (The Ship Avenged, Baen, 1997) imaginative foray into time travel should also please fans of alternate history.
