Fics like The Magic of Genetics

In the aftermath of the war, Harry is dying. An unknown curse courtesy of Voldemort has left him wasting away in a hospital bed. His only hope of recovery is a stem cell transfusion, but no one is a close enough match to save him…until he finds out that James Potter wasn’t his biological father. Now he has just one last chance for life and he is throwing all of his hopes onto one man he has never met. Halfway across the world, Tony Stark receives a specially delivered letter from a terribly sick teenage son he hadn’t known about. Moving before he even has time to digest the information, Tony ignores all the weird and strange things around his son, Harry. At least until he gets him ‘home’ to the Avengers Compound in New York, where they will need to learn to lean on one another and how to become a family.
