Putz's reading.

This explains a lot.

SO I FINISHED JOHN BIRMINGHAM'S Final Impact, the latest in the "Axis of Time" alt-history series.

This is what the cover of Final Impact looks like.



Now what kind of person, browsing in a bookstore, sees this cover and thinks, "Gee -- that Nazi attack helicopter is soooo cool! I've gotta read that!"? I know there's a lot of them based on Amazon's sales ranking, I just don't know who these people are.

UPDATE

A reader below remembers a previous installment of the Putz book-of-the-month club. Here it is again.
