Martin Millar is a fucking amazing read. My three favourites are The Good Fairies of New York, Lonely Werewolf Girl, and Dreams of Sex and Stage Diving. Suzie, Led Zeppelin, and me is also a good read but hard to get into at first.
Also Neil Gaiman, of course, Neverwhere was mentioned, also American Gods & InterWorld.
I'm reading the Discworld series right now by Terry Pratchett, it's fucking funny as all hell. I'm only on book 9. But awesome!
If you've never read Mansfield Park by Jane Austen, get on that shit.
Also Agatha Christie is a regular joyride of reading.
Stephen King is marvelous, as always, I'm almost through with The Stand and it's giving me goddamn chills.
