I've read both the hardcover and the iBooks version of The Fifty Year Sword. The iBooks version contains animation, music and sound effects (the kindle version, apparently, does not). Generally, I would consider this a gimmick, but in the case of this particular book, it worked. The music and sound added to the atmosphere immensely, and the animations were interesting.

This is a short read (took me less than an hour), but well worth my time. I won't reveal anything in this review. There's a storyteller and five orphans, and the tale the storyteller spins is frightening and wonderful. Books rarely affect me so deeply on so many levels.

If you can get the iBooks version, I highly recommend it. If not, then the hardcover (with the stitched pages) is the next best thing.
