I can't remember any time in my life when I wasn't reading a book. :)
Nearly always fiction - I'm not a big fan of biographies or non-fiction. I read all sorts of stuff but haven't actually bought anything for a while - we have a "library" in work where people dump old books, so I've been mostly reading so-so thrillers recently. Can't really give an exhaustive list of "favourite" authors, but I really like Joe R Lansdale, Ramsey Campbell, Robert Aickman, Peter Straub, Michael Moorc--k and I love old classics like Sir Arthur Conan Doyle (especially the non-Holmes stories) and of course Charles Dickens.
Currently reading Congo by Michael Crichton, which is absolute cobblers. His writing style is dreadful.
