Book Recs

So looking for AUDIO book recommendations. Either horror or fictional humour. In other words not David Sedaris or a stand up comic writing a book. For humour something like terry pratchett besides douglas adams. Horror, something more bizarre and unusual and creepy. IE-I do not enjoy anne rice/poppy z. brite; stephen king is great, but i've read almost everything of his; i've done a lot of clive barker already; Dean Koontz...so bad. Horror authors who aren't as well known would be good too.
