Full disclosure: I really don’t tend to like books by Neil Gaiman. I’m pretty sure it’s a personal thing, since lots of other people love his work. I read Stardust after loving the movie based on it, and I preferred the movie almost from start to finish. I tried to read The Graveyard Book, but I couldn’t get into it. And I didn’t get even a chapter into Good Omens before deciding it just wasn’t for me.
That said, I loved Coraline. It’s cute, fun, and just the right amount of creepy. Quite a lot like the movie, if you like that. Very short, so it’s easy to read in a single sitting.
