I think we should take it through Guatemala. A random text from a stranger inspires agoraphobic Colin to leave New York. His first stop is Brownsville, Texas, where he meets the sender, half-Mayan Luci Bolon, her ancient but feisty great-uncle Ernesto, and Miss Mango, a bright-orange Kubota tractor. Ernesto's dream is that Miss Mango be driven to Belize and given to the family he left behind nearly seventy years ago. Colin agrees to join Luci on the long journey through Central America. In 1949, seventeen-year-old Belizean Ernesto falls painfully in love with Michaela, an American redhead nearly twice his age. Their brief but intense affair changes everything Ernesto has ever known. When she leaves, Ernesto is devastated. Determined to find her, he "borrows" a donkey from his uncle and starts off for Texas. He meets a flamboyant fellow traveler, and the three of them—two young men and the donkey they name Bee—make their way to America. The past and present unfold through two journeys that traverse beautiful landscapes. Painful histories are soothed by new friendships and payments of old debts.
