The Reefs of Earth

"The Dulanty family can pass for human, but they're actually alien Pucas, stranded on the remote backwater planet Earth in the tiny (and corrupt) Appalachian town of Lost Haven. The six Dulanty children (seven, if you count the disembodied Bad John) get tired of being spurned, scorned, and scapegoated by the townsfolk, and hit upon the obvious solution: they'll murder every human in the world, using hatchets, rifles, and the otherworldly killing verses known as Bagarthach, and transform the planet into a paradise for the Dulantys alone. Fortunately for the human race, the Dulanty children aren't very adept at murder, but their attempts at wholesale homicide make for a read that's alternately harrowing, hilarious, and heartwarming. Come visit the Reefs of Earth, and experience the incomparable imagination of visionary author R.A. Lafferty, a writer Jo Walton called 'very weird, very clever, and impossible to forget.'"--Page 4 of cover.
