The Boy Fortune Hunters in Yucatan

A party of young adventurers, accompanied by a lieutenant and their Maya guide, embark on an expedition into the Yucatán that moves from coastal stops and jungle traversal to a hidden mountain city inhabited by a surviving Atlantean-descended people. They confront native hostility, novel inventions, ambushes, imprisonment and tribunal proceedings within sacred precincts, and witness elaborate rites and vast buried wealth. Through daring escapes, fights, clever stratagems and appeals to conscience they rescue allies, retaliate against invaders and learn fragments of a vanished civilization while grappling with loyalty, greed and the dangers of pursuing ancient secrets.
