Deep in the rain forests of Guatemala, an ancient Mayan temple holds a mythical secret. The legendary Fountain of Youth lies within, but not all myths are fairy tales. The temple ruins have been seized by the Core, a sinister cult determined to unlock the mysteries of immortality.
When their captured friends are spotted near the temple, Bobby and his cousin Jinx must journey into the dark heart of the jungle to save them. Harnessing their extraordinary abilities, the boys will undertake an epic quest to fulfill a centuries-old prophecy.
Cut off from their allies, Bobby and Jinx combat supernatural barriers, raging rivers, and deadly beasts. They'll face savage natives, vengeful ghosts, and ruthless mercenaries who can conjure a person's darkest fears. Past and present will collide, with the power of eternity on the line. Can Bobby fulfill the prophecy and lay the temple's spirits to rest? If not, Bobby and his friends may become permanent inhabitants of the Temple of Eternity.
