Stephen King's It, The Shining, or Needful Things - are all very different but great examples of the genre.
You might also enjoy some of the early James Herbert novels. My favourite was The Fog and there's also the Rats trilogy (^Rats, Lair and Domain^) but his work is very variable not only in style but also in the quality of his writing. Some of his last works were, in my opinion, poorly written tosh!
Have a look at Dean Koontz's books, too. Not everything he's written is horror; some of it is utter drivel, most of it is plain weird but there are some utterly gripping page turners: look him up on Amazon and check out some of the reviews.
You could also try Adam Neville or Mark Edwards ... there are loads out there so try asking at your local library if you don't want to make an expensive purchase which you may then hate.
