From New York Times best-selling author John Connolly comes a compelling and imaginative novel about a boy and his dog struggling to escape the wrath of demons. Samuel Johnson is in trouble. It's bad enough he's in love with the wrong girl, but the demon Mrs. Abernathy seeks revenge for his part in keeping diabolical forces from invading Earth. And when Samuel—and his faithful dachshund, Boswell—are pulled through a portal into the dark realm, she gets her chance to sink her claws into him.
