I read a book years ago that was about a hunchbacked boy. I remember there was space travel, a ship, a female and other characters.
I also remember he had an incredible itching on his hump. He was helping someone then his hump split open and he had wings. His name was Fayrei or Fayrie, I can't remember what he was called before he told his name.
There was a sequel when he started looking for his own kind.
