Max and Mandy have been taken captive by the very beings they were searching for, Atlanteans, that is, teenage Atlanteans around their own age of seventeen. After reluctantly agreeing to their terms, the five set out on a mission to save the planet, but their odds aren't good. Unbeknownst to them, there is a traitor in their mist who is working with the powerful Atlantean, Bharákys. His hatred for the land people will allow his army of man-eating Drexins to wipe out all human life. Then there is Preston, the richest man on the surface world. He is determined to set the nations against each other by remotely releasing their nuclear weapons, thus leaving the survivors for him to rule and begin his new world. Their loyalty, strength, and compassion will be tested to the fullest, but one small mistake could shift the tides...and kill all life on the planet.
