Amazon.com description: Product Description: Chris scoffs at his younger brother's enthusiasm for collecting rocks-particularly one Nick thinks is shaped like a turtle-and generally thinks that the eight-year-old is something of a wimp. But Chris's attitude is dramatically changed as the brothers suddenly find themselves trapped at dusk in a deep forest with eighteen-century fur traders. With the help of his turtle warrior rock and his new friends, Meggie La Framboise and her assistant LeClaire, Nick saves Chris from the clutches of an evil trader named McDougal. But the boys' adventures have only begun as they flee from McDougal to an Odawa Indian camp and then on to Mackinac Island. Traders in Time vividly portrays the variety of people involved in the fur trade and brings to life the sights, smells, and drama taking place along the shores of Lake Michigan and at Fort Mackinac in the late 1700s.
