Just love Neil's stuff, whether novels or comics or short stories. Well worth picking something up by him if you're unfamiliar, especially Stardust, the Graveyard Book or Sandman.
Everything Neil Gaiman does is fantastic, in my opinion. He is a masterful storyteller, creating dark, fantastical worlds that capture your imagination.
Neil Gaiman is one of the most interesting authors I have ever read. The Graveyard Book is great and I can't wait until my children are old enough to handle it as he does tend to have quite scary imagery.
He has a wonderful writing style that is humorous, dark, filled with great characters, and simply brilliant. I have read several of his works and have yet to find one that I didn't like.
