As revolutionary forces gather in the Lacandon jungle of southern Mexico in the fall of 1993, an idealistic American priest vanishes from his post in San Cristóbal de Las Casas. The Church, immersed in trying to negotiate a peaceful solution to the escalating conflict between wealthy landowners and poverty-stricken indigenas, remains strangely silent in the face of his disappearance. When his sister, Eva, only thirty-four but already a hardened battlefield photojournalist, finds out what"s going on, she flies to Central America to find him, taking a job assisting a taciturn Dutch Mayanist in order to provide herself with a cover. But as it turns out, he, too, is on a secret quest. From the great pyramids of Tikal and the graceful palaces of Palenque to the shadowy guerrilla camps of the vast Lacandon, A Land Without Sin is a modern-day journey into the heart of darkness.
