I recently read all of John Allison's webcomic Bad Machinery. In one sitting. Yes, it is that good!
It follows the adventures of 6 private school children in England who have a propensity for mystery-solving and discovering fantastical beasts in their midst.
I like the humor, the art style, the characters, and the somewhat surreal alternate reality that exists in the fictional Town of Tackleford.
You should read this!
