Saving Strangers (Rewriting)

Warren has never known who his parents were. That is until he gets a visit from a couple telling him they knew his parents and that they died but now the couple need Warren's help. Warren's mother and father were two of the best spies/assassins in the world, they died on an op and nobody ever knew they had a son. But now his parent’s old company is in trouble and he's the only one that can help but he doesn't know how. Warren grew up moving from foster home to foster home until he was fifteen and had enough, then he ran away and lived on the streets for a year before he was picked up by Mickey Connor, infamous gangster and all round bad guy. Warren has severed his ties to the gang but they aren't happy about it and are determined to get him back, any way they can. Now add the problem of having to look over his shoulder for enemy assassins and his life just got that much more complicated.
