Gotham's Hope

Perseus and Elpida Jackson have been through together in thick and thin... well, except for that time in hell where Ida got captured trying to help Percy and Annabeth escape, but they mostly stuck together. Now that bond is tested more than ever. With their mother gone, and severe mistrust being spread throughout camp about Ida and the violent mysterious powers she got from her time in hell, she is forced to leave, and the siblings move to Gotham, one of the few places Ida wouldn't be hunted, but that's not what Percy wants. While he loves his sister, he wants to go to New Rome and be with Annabeth, so he stays in Gotham once a month and the rest of the time at collage.
Got all that? Good.
The bats are a suspicious bunch. Always have been always will be. When Tim meets the new girl, Elpida Jackson, he can't help be suspicious of the girl who used to be a terrorist, no matter how much Damian likes her, which is even weirder. They get more suspicious when they on patrol in one of the bad parts of Gotham they hear a scream and find the same girl waking up, shaking... alone? Where are her parents? Wait, she doesn't have any. Then where is her brother?
When weird, even weirder for Gotham things begin happening, and Ida begins to discover what she can really do, the two worlds collide, well more than they had all ready collided, and, well, shit's about to go down.
Here we go again.
