It's not on any chart, but the tropical island of Cayo Loco is the perfect place to run away from all your problems. If you're looking for a license to chill, come along as cowboy Tully Mars takes his pony to the shore - on an unforgettable Caribbean adventure as colorful and wonderfully bizarre as cocktail hour at your favorite expatriate bar. From a lovely sunset sail in Punta Margarita to a wild spring-break foam party in San Pedro, Tully encounters an assortment of treasure hunters, rock stars, sailors, seaplane pilots, pirates, and even a ghost or two. Waking from a ganja buzz on the beach in Tulum, Tully can't believe his eyes when a 142-foot schooner emerges out of the ocean mist. At its helm is Cleopatra Highbourne, the eccentric 101-year-old sea captain who will take him to a lighthouse on a salty piece of land that will change his life forever.
