What You Love Will Always Come Back

Sirius and Severus had a son together, but he was ripped away from his fathers at 3 months old. Severus is convinced that their son is dead. Only Sirius knows what actually happened that night. Alas, he is in Askaban. Harry Potter is from a decent size family, you'd think his life is perfect, but it's not. Harry just wants a family to actually care about him. Tomarry/Harrymort.
