Stephen King
Richard Layman
Dean Koontz
JK Rowling

I just read all of them over and over again - I think I am onto my 3rd copy of some Stephen King books

And I've never read anything else by Harper Lee, but "To Kill a Mockingbird" is, I think, my all-time favourite book ever. My copy is very battered, and pages have come unglued, but I still love it!
