I'm looking to identify a sci-fi book I read a few times as a tween / young teen in the 80s. Set in the future where jobs are predetermined and the body is manipulated accordingly. The main character is a young man who is a gardener, and his (probably left) hand is shaped into secateurs. The cover art had him with his love interest, and he had the secateur hand on her shoulder, I think.


The only other thing I remember is that the weather could be controlled, so it only rained at night.
