There is the known and the unknown. And then there is the unknowable.
A rumor around Atlantis whispers that the mighty crystal has the power of resurrection. Fourteen-year-old Shu-Tu believes this to be true and will do whatever it takes to bring her father back from the dead. Recruiting two trustworthy classmates, and with the help of her beloved teacher Thoth, Shu-Tu sets out to change her father’s fate, and right a wrong.
Instructed to meet Thoth at his grotto, Shu-Tu and her friends are forced to flee underground, and must follow the maze of passages to find another way out. There, they come across a baboon-headed human hybrid possessing a rare firestone—one of six harvested from the mighty crystal—which has the power to restore life. Shu-Tu agrees to play the hybrid’s bizarre game to win the firestone, knowing that if she loses, she loses her father forever.
