Wisp has a learning problem: he can’t read stars. For a juvenile nighthawk bursting with wanderlust this means trouble, with his peers, his parents, and the starving colony that tries to fence him in. So he ditches everyone, striking off on a forbidden migratory journey from the Amazon to the Arctic, alone – or so he thinks. Crossing two continents, he wings above South America’s soaring Andes Mountains, over the belching mouth of Mexico’s Popocatépetl volcano, across the searing Arizona desert, up to the steaming Alberta tar sands, then steers farther north than any nighthawk before him. Can Wisp beat the odds against him? Without the help of stars, can he navigate one of the longest, most treacherous migration routes on Earth?
