An Inconvenient Herd [EPUB ebook] 

SOMEONE LETS FARMER’S COWS OUT. Fueled by idealism and curiosity, the herd follows a bike path into the big city, chasing a dream of a new way of life. The good-natured cattle make lots of friends, but life in town is complicated. They encounter religion, local politics, and manicured lawns. Meanwhile, Farmer is frantically searching for the wayward cows, racing to save them from the perils of celebrity and the urban machine before it’s too late.
