Testing the Prisoner is now on KindleGraph!

Testing the Prisoner has now been listed with KindleGraph.  With KindleGraph, you use your Twitter account to request an author's signature on one or more of their eBooks. You then apparently receive a document downloaded to your Kindle containing the author's signature, or something like that.  It may work on more than just the Kindle, I'm still figuring this thing out.  More info is forthcoming...
