The Healer — J.L. Bowen

Thirteen-year-old Armond Costa heals in three days, no matter what abuse his uncle and aunt inflict upon him. On his fourteenth birthday, he sprouts wings and discovers his aunt and uncle had lied to him. He's the lost Golden Demon's Healer. His father, King of the Golden Demons, insists he return with him and save his people from being persecuted by their mortal enemies, the Dark Demons. Now, Armond must choose between the Ellis brothers and seventeen-year-old Rusty Owens -- the only family he's ever known -- or condemn the Golden Demons to extinction.
