Shadow the plucky fox and a girl named Bee might be the only ones who can save a secret magical island in the Great Lakes. Shadow the fox does not trust humans. Well, except for Nan, who feeds her chunks of fish behind a lakeside motel every night. When Nan goes missing, a man from the mysterious Whistlenorth Island comes ashore to seek the aid of Nan's granddaughter, Bee, whom he thinks is destined not only to help Nan, but also to save Whistlenorth from the greedy and destructive Night Islanders. The plans go topsy-turvy when it becomes obvious that Bee does not have the magic powers of a chosen one—but Shadow does! Can a fox really rescue an island of people? As Shadow grudgingly comes to trust her new human companions, she and Bee develop a mystical bond, a special connection between human and animal that might be the key to driving the Night Islanders from Whistlenorth for good. This enchanting adventure is narrated by Shadow herself, whose mind is unflinchingly "fox" and whose spirit is charming and bold.
