I knew there was a book I read in January 2009 that I was totally missing in this whole keeping track of books I read. So nice to know that I wasn't misremembering I had read five books... just misremembering what that fifth book was. =)
5. THE STEPSISTER SCHEME by Jim C. Hines
Great fun and I can't wait for the next one in the series. I actually went and wrote a review of it on Amazon, which should be up at some point.
