An Illustrated Book of Bad Arguments by Ali Almossawi. Non-fiction. Hardback, 55 pages. Keeping it to push around the office.
This is a reasonably accessible book of argument decomposition. It does require a fair amount of vocabulary (e.g. "fallacy, refuting, idiosyncratic") as well as a general understanding of causality. I didn't find the illustrations to be all that useful, though they were generally cute.
I plan to take this to work.
I thought I picked it up because of Unshelved. Turns out, it was a random Amazon recommendation from the books I purchased for my nephew.
