The Jaguar Stones

Fourteen-year-old Max Murphy is looking forward to a family vacation. But his parents, both archaeologists and Maya experts, announce a change in plan. They must leave immediately for a dig in the tiny Central American country of San Xavier. Max will go to summer camp. Max is furious. When he's mysteriously summoned to San Xavier, he thinks they've had a change of heart.

While everyone else is panicking about the so-called end of the Maya calendar, 14-year-old Max Murphy has his own problems. He owes a favor to the ancient Maya Lords of Death and now they’ve called it in. Max has just seven days to bring the long-lost Yellow Jaguar to Xibalba, the cold and watery Maya underworld.

A hurricane is brewing in the jungles of the Maya, and the ancient Death Lords are on the warpath. Across the world in Venice, Italy, hanging out with his blogger friend Nasty (Anastasia) Smith-Jones and eating Pizza Gelato, Max Murphy thinks he is safe from their clutches. But when a rogue octopus pulls him off his gondola and tries to drag him down to the underworld, Max realizes that the Death Lords have not finished with him yet.
