Cowboy Tails: A Molly and Grainne Story

...Twelve-year-old Molly O'Hare lives a different lifestyle than the average kid. She lives in a bus; with her parents, and a seven-foot-long Irish Wolfhound service dog named Grainne. Molly's parents work as travel writers for a magazine, and the family is on a long expedition to discover the best vacation spots, in the United States and other countries, to write about. It's the beginning of their adventure, and things are not off to a smooth start.
