A hungry fox and a girl with a lively personality wield magic togetherEvents unfold from the viewpoint of the narrator, a fox named Shadow who lives near the shore of Lake Superior. Food is scarce, she's thin and has patchy fur, and the loss of her sister some months before is constantly on her mind. Shadow steals shoes from rooms at a nearby motel-she has 257 piled in her den-and distrusts all humans except for one. But Nan, the white-haired woman from the motel who used to feed her, is inexplicably gone; a red-haired girl is there instead. Bee, Nan's granddaughter, is a bit wild and out of step with others herself. To Shadow's initial annoyance, she and Bee forge a bond that turns out to be deep and magical; indeed, Bee can understand and give human voice to Shadow's thoughts. Meanwhile, the island of Whistlenorth, accessed through a portal on Lake Superior, is the site of imminent (and foretold) devastation-and Bee and Shadow must attempt to thwart the danger. The Night Islanders' greedy and indiscriminate reaping of the environment to distill "ultra-concentrated magic" has laid waste to much of what grows in the magical islands and threatens Minnesota's forests. As Shadow navigates the dangerous territories of trust and power, the fox has a compelling voice that's prickly, proud, and subtly funny. The book convincingly depicts a singular brand of northern, woodsy, wild magic.An appealing combination of animal magic and low-key hero fantasy.(Fantasy. 8-11)
