The Hellbound Heart, by Clive Barker: This is the book on which Hellraiser is based. For the most part, the book followed pretty much the same lines as the movie, except that Kirsty was not Rory's daughter. I'm not sure why that was changed for the film. Also, while there's a reference in Hellraiser 5 to Pinhead as "The Engineer," the book makes the Engineer someone different. I think that's just because of how Pinhead basically ran away with the series, though. The book makes the Cenobite who would eventually become known as Pinhead an androgynous figure, which wasn't the case in the movies.
Slaughterhouse-Five, by Kurt Vonnegut: I'd read and enjoyed other books by Vonnegut, but not this one, although I've had a paperback copy without a cover for several years now. It was a very quick read, as are most of his books, although I don't think I ever made it past the first chapter of Jailbird.
America (The Book): I found this kind of similar to Dave Barry's takes on American history and politics, although there's less of a reliance on running gags and a higher budget. While Dave Barry Slept Here parodies a history textbook, America actually LOOKS like a textbook, complete with all the requisite crap in the margins. Of course, the important question with a parody book is whether it's funny, and the Daily Show book is, so no worries there. The version I read is the paperback Teacher's Edition, which includes "corrections" written in red ink by someone pretending not to get the jokes. This gimmick is okay for a little while, but it gets old fast.
