A Boy and His Dog at the End of the World

Teenager Griz, his two dogs, and the rest of his family live on a small island off the west coast of Scotland. His family has been there since the Baby Bust, a global epidemic of infertility that left the earth almost entirely depopulated. They lead a simple life of farming and fishing until a traveler arrives to trade scavenged equipment for food. The family is suspicious but lets the man ashore. Griz wakes up the next morning from a drugged sleep to see the stranger's vessel sailing off with their supplies and one of his dogs. Griz and his remaining dog Jip leap onto his small boat and give chase. But things don't go quite as expected, and he and Jip end up on the mainland of Britain, which is not as empty of people as he'd been led to believe. Griz is still determined to get his dog back, however, and the many dangers and surprises might slow him down but won't stop him.
