Bring Me Home, Necromancer

Remus has seen spirits as long as he can remember, helped them cross over since he was a boy. No one, not even his boyfriend, has ever known. His disguise can't survive the death, and subsequent return, of his murdered best friend. Sirius is raising his child now, and James won't leave until he talks to him. Remus isn't ready to be exposed, but who ever is? Non-magic AU
