Hello, I really enjoy reading
Have you read The Chronicles of Thomas Covenant written by Stephen R. Donaldson?
I haven't. It sounds interesting though. What genre of book is it?
They are high quality fantasy novels. 
Awesome. Who is the author?
I already told you that earlier, but the book is about a cynical writer that has leprosy, an outcast from society that saves the land!
So you did. Sorry! Where does this take place? 
It takes place in an alternate world.
Why was the cynical writer an outcast?
Probably because he has leprosy. In the novels his arch enemy is Lord Foul, "The Despiser".
I guess they don't have a treatment for it! How did he go about saving the land
