Mortal Savior

Benjamin Blackston is a mortal with two half siblings. His mother died when he was young so he is being raised by his father, when suddenly the world of Greek mythology becomes all too real. His siblings' missing parents are missing no longer, but he is still a misfit.
But with a new Great Prophecy, the gods must each find 2 heroes, one male, one female. After almost no training, he is given the opportunity to join the Hunters of Artemis, something that few males have ever had the chance to.
With his world changing, and that of the gods, he must rise to the challenge in order to save both his friends, family, but, most importantly; the gods.
