Everything that could go wrong in Percy Jackson's life did. A single different action everything, leaving Percy alone after losing so many of his loved ones. His friends were dead. His stepfather was dead. His mother was dead. The love of his life was dead. And the last person left, his sweet little sister was taken away by social services. Before the police could put him into the hands of social services as well, he runs away. Away from the brutal world of mythology and to the only place it couldn't reach. Gotham City. Fortunately or maybe unfortunately, that's also where his sister has been sent as well. However, getting his sister back might not be as easy as it seems despite being away from gods and monsters, not when Gotham City is filled with heroes and villains who all seem to have taken a liking to him. And why the heck does Bruce Wayne want to add him of all people into his merry band of black haired orphans?! ***PJO & HOO spoilers, there also might be slight mentions of some of Rick Riordans other books, but seeing as this is canon divergent it might be more so mentions of characters than spoiling events.*** *This is a (hopefully) better rewritten version of a fanfic (A New Family) that I started writing back in 2020 for fun. I had to stop writing it for a while despite having a lot of it planned out. I never planned on dropping despite how long it's been, however after going back and rereading it after finally having the time to continue, I found that I my writing changed a lot and I could better plan out some things. So yeah.*
