Fics like Congratulations! It's a boy, and it's not yours!

Bruce Thomas Wayne would like it to be take off the records that his first thought when finding out his son has a biological brother was “when the hell did I had another child?” Sally met Talia on a lazy afternoon at the beach, two weeks later she met Poseidon, and nine months later she met Percy. Born of love and magic, Perseus al Ghul-Jackson has two amazing mothers, a slightly murderous grandfather from his maternal's side that's way better than the totally murderous grandfather from his dad's side, one deadbeat father that is trying and failing but still trying so he gets cookies points, and a Paul. He also has two and a half brothers that he loves, a little sister that he adores, and way too many relatives to pretend he likes. Now, on top of it, he also has a weird bat-guy and his cauldron stalking him from rooftops and being overly dramatic about it.
