The Hydro Gene by Chase Peter Josef

David was sure that the most exciting thing that would ever happen to him was contacting honest-to-god aliens on his homemade subspace communicator. Too bad he died of a heart attack a second later.

Then he’s resurrected.

In this contemporary fantasy, David discovers that aliens are just the beginning of what awaits him out in the universe. Together with the new acolytes of love, war, truth, and more, he charges into battles straight out of myth. As David fights the Hydra, traverses the river Styx, and encounters the snake with no end, he gradually realizes that their godly mentors are hiding some secrets of their own. In this mysterious world, the biggest question is still unanswered. Why do none of them wonder what is going on?
