I was just looking at the Machiavellian Librarian on Amazon.com (because I really don’t have a life) and its finally listed as being available for the Kindle! This just appeared mysteriously with no notice, as the publishing world works in strange and mysterious ways. So you can now buy it for your Kindle for $64.00 US or you can buy the paperback for $70.84! Or you can buy it for your Nook from bn.com (haha, no really) for $80.00.
