Mexico, 1924.

At his father's hacienda, restlessly waiting for adventurer Ethan to arrive, sixteen-year-old Alec and his faithful valet Coates head out into the wilderness in search of an ancient archaeological site . . . only to discover that Mexico is every bit as perilous as The Valley of the Kings.

Pursued by ruthless bandits, involved in a plane crash in the middle of remote rain-forest and finally an unwelcome guest in a lost Aztec city where the inhabitants still practice rituals of human sacrifice, once again Alec must use all of his skills and stamina to survive.
