I love reading Robertson Davies because for once I don't have to translate the Americanisms into Canadianisms for a meaningful understanding! I have devoured all his fiction, except for The Diary of Samuel Marchbanks, and recommend them highly to anyone I meet.

Re: John Bellairs. I love his books! I am also too scared to read them again! I have too much imagination and his scary ghosty things seemed SO REAL the first time around, that I am reluctant to re-read them. While on the subject of great young adult books, I suggest "Hatchet" by Gary Paulsen. I've read it many times and it still amazes me.
