Anna Pigeon, a ranger for the U.S. Park Services, sets off on vacation-an autumn canoe trip to the Iron Range in upstate Minnesota. With Anna is her friend Heath, a paraplegic; Heath's fifteen-year-old daughter, Elizabeth; Leah, a wealthy designer of outdoor equipment; and her daughter, Katie, who is thirteen. For Heath and Leah, this is a shakedown cruise to test a new cutting edge line of camping equipment. The equipment, designed by Leah, will make camping and canoeing more accessible to disabled outdoorsmen.
