An unearthly being has burrowed in Sally May's vegetable garden. Hank tries to dig the space monster robot out of its hole. But when Sally May catches Hank in the ruined garden she blames him. Ashamed, Hank hits the road. Beginning his exile he runs into his old friend, Madame Moonshine. Will she help Hank clear his good name?

John R. Erickson, a former cowboy and ranch manager, is gifted with a storyteller's knack for spinning a yarn. Through the eyes of Hank the Cowdog, a smelly, smart-aleck Head of Ranch Security, Erickson gives readers a glimpse of daily life on a ranch in the West Texas Panhandle. This series of books and audios is in school libraries across the country, has sold more than 8 million copies, was a Book-of-the-Month Club selection, and has won an Audie for Outstanding Children's Series from the Audio Publisher's Association. Publishers Weekly called Hank a "grassroots publishing phenomena," and USA Today said this is "the best family entertainment in years."
