Note that these books are re-release versions, hence the release date in year 2006.
If you're really observant, you'll notice something strange on pages 118, 119, 122, 123, and 124, the first time you read through. Don't think about it too much, though. You can always come back to it afterwards. If you don't notice it even after going through it once, umm, you need to jump start your brain.
It's getting a bit too unrealistic here and there. I have nothing against fantasy type unrealism, but forced realism type doesn't work well with me. It's still funny and the art is great.
