I read and enjoyed the first book of the Silo Trilogy almost two years ago. Now I've finally read the second book (Shift) and I'm about to start the third (Dust). The most I can say about "Shift" without spoiling the story is that it is a prequel explaining how the world came to destruction and how the major characters of "Wool" reached the positions they have in that book. Again I was impressed with the careful planning and construction that Howey has put into the story and I'm eager to polish off the series.

I saw Logan, possibly the best X-Men movie to date, on opening night. Later I picked up a used copy of the graphic novel on which it was (loosely) based and read it in an evening. It was also good, but almost nothing like the movie.
Instead of mysteriously disappearing like in the movie, almost all of the mutants were wiped out by the coordinated effort of all of the super-villains. Those villains then divided up America for themselves, resulting in a post-apocalyptic wasteland in which Wolverine (Logan) is simply trying to live with his family in peace. The Hulk family rules the part of the world he lives in, and when Logan can't make the rent he's forced accompany a very old and very blind Hawkeye as a mercenary on a quest across the country to make a quick buck.
The journey is mostly an excuse to show off the fate of all the characters in the Marvel universe in this alternate, dystopian timeline. It's bonkers and a lot of fun.
Some people find Franzen's writing intolerable and hacky, others call him one of the best contemporary American writers. I'm not sure I can pass judgment either way, but I enjoy his stories.
I can't quite say what Purity, his latest novel, is about but it definitely entertained me. The characters are interesting and provide convenient excuses to explore a variety of times and places: cold-war-era East Berlin and Pennsylvania; the rain forests of Bolivia; present-day Oakland, Denver, and the Santa Cruz Mountains. One of the major themes is the ability of the Internet to increase the transparency of governments and corporations via Wikileaks-like organizations, and how that compares to "legitimate journalism." But more important is the book's slow reveal of the connections between a disparate collection of people and how it affects them.
If you're interested in Franzen check out his best, "The Corrections," first and if you like it then come back to this one.
