Percy Jackson, cursed to be a monster

Percy and Annabeth couldn't be closer after the giant war. As they enjoy a picnic they're attacked by dragons. Percy gets bitten and ends up as one of them. He runs away hoping to escape Annabeth leaving him, his friends following her lead and Tyson not even being able to look at him. A new snobby camper gets added to the mix and what do you get? An angry dragon who could destroy the gods.
