The story takes place after the staff of Hermes Sally and Paul were murdered, leaving Percy with his newly discovered uncle, Bruce Wayne. This is the same time as when Dick and Bruce's relationship is strained. He was going to go on is own as Nightwing, later on. Artemis is sending Thalia to inform Percy about a new quest. She knew Apollo will have to go against the Triumvirate in the future. Percy will have to work with Annabeth to stop their weapon income. They'll go against the Penguin. I've never seen any plot like this, therefore, it's original.

After the defeat of Gaea in the second war, Percy Jackson needed a rest. Unfortunately, "rest" seemed non-existent to Percy's life when he arrives back at his apartment to find his mother and step-dad dead. With their deaths came along a threatening note. With nowhere to go, the authorities did their best to locate a relative and discovered an uncle who happens to be the billionaire, genius and superhero, Tony Stark. But with the threat, the death of his parents and a whole team of superheroes weighing down on him, Percy knows he's far from the beginning of a new danger.
