Oh my, PatH, what an emotional response to Wool. The first, it pretty much sets up the structure of the silo community and the practice of sending dissidents and convicts out to clean the one window to the outside world - essentially a death sentence. There are some interesting surprises in the following books, and as begun in the first book, a growing suspicion that the powers are keeping secrets. Beyond that, I don't want to introduce anything that might be a spoiler. It is not my usual SciFi type reading, but the story grew on me quickly. I've heard some noise about Wool being made into a movie, but I haven't checked on its status lately.
A Talent for War is the first Alex Benedict book; Polaris is the second. Seeker, the third, won the 2006 Nebula Award for Best Novel. The Devil's Eye, Echo, and Firebird are next in that order. The newest of the series is now due out sometime in 2014. I could have sworn it was originally due out this fall - didn't happen. It is listed as being titled Coming Home. That title has a final of the series ring to it. I hope not, but at 81, Jack may want to wrap up his series. I have not yet read any of the Priscilla (Hutch) Hutchins series yet and only one of his stand alones (Eternity Road) so far.
I am happy to say that the new generation of SciFi writers have some stars among them. Aside from Hugh Howey I would could Evan Currie. I have finished with his Warriors Wings series (more to come) and am in the middle of the Odyssey series. Aside from the obvious penitent of the ebook writers to not have their work properly proofed for misspellings, etc. his books are good. The Warriors Wing series features many women in positions of command giving rise to one fleet to be called the Valkyries. The primary role in ground based operations is also a woman. Currie has a new series started called Seal Team 13 which I may or may not follow. He also wrote a stand alone (so far as I know) called Steam Legion which goes back to the early Roman Empire. All of Currie's books are, so far, only available in ebook form and only available on Amazon because he uses their digital services to publish his books. That is a bummer for those that don't use Kindle that might like to read his work.
