Horizon at the End of an Ocean

Sequel to my previous story "5 Times Tony Denied Having a Kid." This is a stand-alone, but I suggest reading that first. After May dies, Peter is taken in by Tony Stark. They try to manage their new lives, deal with their relationships with others,and keep their heads above water. Tony, if being honest, has no idea how to raise a teen. Can he do this without screwing everything up?
