Philip Dick Award Winners

I'm quite intrigued by the joint winners of this year's Philip K. Dick Award, Adam Troy-Castro's Emissaries From The Dead and David Walton's Terminal Mind. The former I was peripherally aware of, primarily because I picked up Harper Collins' free download last year (mind you, the online page is a bit confusing since it seems to suggest the free download is still available ... and then a few lines later tells you actually, no, it isn't), but haven't yet read it. That it's won an award may spur me to get round to that sooner rather than later. Walton's book is interesting primarily since I've just never heard of it at all, but based on the description, it sounds pretty interesting.
