Based on a true story, The Jaguar's Heart brings to life the first encounter of Maya and European in the 16th century.

It tells the story of Gonzalo Guerrero, a Spanish sailor shipwrecked on the coast of Yucatan in 1511, between Columbus' discovery of the Americas and Cortez' conquest of Mexico. Maya lords enslave Guerrero and his fellow castaways, but he eventually gains his freedom. Encountering Ix Chan Can, the beautiful younger sister of the Maya lord Nachan Can, Guerrero chooses to remain among her people and win her love. Guerrero earns renown in a war against Nachan Can's enemies, and finally Ix Chan Can's hand. After they have two children, the only other still-living castaway, the clergyman Jeronimo de Aguilar, brings word of Cortez' landing. Guerrero refuses to rejoin his countrymen, cleaving to his family. But with Aguilar as interpreter, Cortez conquers the Aztecs, and the Spaniards inevitably return to impose their rule and religion on the Maya. Nachan Can now demands that Guerrero fight, and at last accepting that he must do so to protect his family, Guerrero tragically stakes his life for his adoptive people against ever-mounting odds.

The Jaguar's Heart reveals the struggle of a man caught between cultures and conflicting loyalties at a pivotal moment in the history of the Americas. It is a book with the captivating setting of Gary Jennings' Aztec and its sequels, yet which reveals the humanity of both Spaniard and Indian, and with the compelling theme of W. Michael Gear and Kathleen O'Neal Gear's Contact: The Battle for America series.
