When Jason set out to find his father, he could never have anticipated where his journey would lead...Far from home and desperate for answers, Jason washes upon the shores of an ancient land. A mysterious place; a world of bull leaping, of snake haired goddesses and of palaces so vast it was said they were built by giants--this is the lost city of Atlantis. Aided by the studious young Pythagoras and the overweight, overbearing Hercules, Jason embarks on a voyage of discovery that sees him brush shoulders with Medusa, come face to face with the Minotaur and even fight with the dead.

Battling their way through a vast store of myths and legends, the unlikely but loveable trio gradually begin to uncover the dark and simmering past of Atlantis, and it soon becomes clear that both friend and foe can be found in the most unlikely places...
