Karma Wilson is the New York Times best-selling author of Bear Snores On, whose children's books are a pure delight. One day on the farm, two crazy cows, Mabel and Molly, take Farmer's keys from his back pocket when he isn't looking. And just like that, the cows start-up Farmer's car and drive away. Look out everyone! It's a cattle drive! Mabel and Molly don't exactly know how to drive, or read road signs, but wouldn't you know it, they're on their way to town for an adventure.
