Snow White and the Seven Samurai by Tom Holt

If you like Terry Pratchett or Jasper Fforde, Tom Holt might also be up your alley, filled with what I like to think of as British humor--rather dry and self-referential.

Our story begins with the wicked Queen's mirror, but when the Queen steps out for a moment, three kid-hackers break into the fairy tale reality and quickly set everything amok when they crash the Mirrors (computer) system.

With plenty of puns and loads of fairy tale references, though mostly well-known tales, this is an enjoyable read. The story is a bit disorganized and the ending is not as fully satisfying as I hoped it would be. However, seeing the stories come together and clash is always one of my favorite things to do, and this book is chock-full of that. If you like mashups of multiple stories, this is a fun one.
