My favourite in the horror genre is Shaun Hutson. I was introduced to his books by a flatmate in London many years ago. The link for me was that all his stories are based in and around London and as I was living and working there at the time, it kind of got me hooked. Managed to buy a few autographed copies of his books as he had done a book signing the day before I found this particular shop. Oh well, nearly met him. Funny thing is, I only ever find his books in the bargain sale bins here in Sydney, don't know why. I currently have 21 of his books on my bookshelf.
