Percy Jackson: Birth of Helphius

Percy Jackson is your normal 27 year old. That is, if you can call the greatest hero of the 21st century normal.

He is the celebrity of the Twilight world inhabitted by gods, warriors, and monsters, but Percy wants to be away from all of it. So he's finally happy when he and Annabeth settle down in the Mortal world.

But trouble is brewing. A mighty immortal rises, birthed from the blood of the children of the Big Three.

Now Percy and the rest of the children of the Big Three are in trouble, and things aren't helped by the fact that the Olympians have exiled them from both camps. This time they have no army, no allies... only each other.
