Currently free for the Kindle: Wodehouse parody.
As I'm never one to turn down anything Wodehouse—and that goes triple for anything FREE and Wodehouse—so I just 'bought' the hell out of Whimsy & Soda.
Full disclosure: Do you have to bother with full disclosure when recommending free stuff? I dunno. Anyway, I used to work with the author's wife. And I interact with said author on the FB on a pretty regular basis, though we've never met in person.
