Beginning in the Yucatán-and moving south through Belize, Guatemala, Honduras, Nicaragua, Costa Rica, and Panama-Wood's journey takes him from sleepy barrios to glamorous cities to Mayan ruins lying unexcavated in the wilderness. Wood encounters indigenous tribes in Mexico, revolutionaries in a Nicaraguan refugee camp, fellow explorers, and migrants heading toward the United States. The relationships he forges along the way are at the heart of his travels-and the personal histories, cultures, and popular legends he discovers paint a riveting history of Mexico and Central America. While contending with the region's natural obstacles like quicksand, flashfloods, and dangerous wildlife, he also partakes in family meals with local hosts, learns to build an emergency shelter, negotiates awkward run-ins with policemen, and witnesses the surreal beauty of Central America's landscapes, from cascading waterfalls and sunny beaches to the spectacular ridgelines of the Honduran highlands. Finally, Wood attempts to cross one of the world's most impenetrable borders: the Darién Gap route from Panama into South America, a notorious smuggling passage and the wildest jungle he has ever navigated.
