An Atlantean Apocalypse

For hundreds of years, Atlantis was thought to be a myth, a mere legend spun by the people of history to entertain. But a rare journal entry is found, dating back hundreds of years. Its a man's journey to safety through the destruction of Atlantis.
And with him there is a child and a infant. The infant carried an amulet, which according to the journal entry, holds a secret map to Atlantis.
And coincidentally to the Fountain of Youth.
But, further readings give proof that the Fountain of Youth isn't all that its said to be. That it isn't really a fountain, but a weapon.
And a group called The Divine want it.
Enter Julian Archer and Cameron 'Mac' Heard, two 'fortune hunters' who will soon find themselves racing to save the world.
