From the #1 bestselling, award-winning author of The Golden Spruce and The Tiger: a rich, gripping literary thriller in the spirit of The Constant Gardener that showcases the narrative power for which John Vaillant is internationally acclaimed. Hector, a young Zapotec fleeing Mexico for a better life in the US with his friend Cesar, a biotech researcher, pays to be smuggled across the border by unscrupulous "coyotes," concealed in the tightly sealed, empty tank of a water truck packed with illegal migrants. Abandoned by the smugglers in the desert, they are left to die, their only lifeline Cesar's phone. When Cesar slips into unconsciousness, Hector reaches out to the one name with an American code--AnniMac--that becomes his lifeline to the world as he reveals what has brought him to this place, taking us back to an older Mexico; to the lives of his Zapotec grandparents and the ancient, mythic traditions, to the mystery behind the jaguar icon left to him by a mysterious archeologist, and the power of the corn myth. As legends fuse with the terrifying present, the dangers Cesar is fleeing become grippingly apparent: his research was threatening to expose the country's largest manufacturer of genetically modified corn, set to impose economic and cultural genocide on the native population. Finding the courage to survive is critical, even as hope dwindles.
