Dust is the final volume in Hugh Howey's Silo trilogy, which began with Wool, jumped backward to prequel Shift, and has now returned to the "present" for the finale. It picks back up with Jules and Silo 18, Jimmy/Solo and Silo 17, and the folks inside Silo 1. Jules is engrossed in trying to burrow her way back to Silo 17 to rescue Jimmy and the kids, and all the while dissent is growing in her own silo because she's basically challenging the world order. Jimmy is waiting for Jules, and then eventually unnerved by what has happened with the silos being connected. And in Silo 1, the truth is starting to come out about who is awake, who is asleep, and who is dead...and what it might mean for all of them.
I don't think that Dust was the greatest conclusion to this series. Wool and even Shift were so twisty and full of surprises, and Dust just...wasn't. The story is pretty straight forward here, with everyone's intentions all out in the open after the drama after the first two books. While the actual writing hasn't deteriorated in quality, the fact that there weren't as many "OH MY GOD" moments meant that this wasn't as riveting a book as the first two were. I also had more problems with the logistics of this one; I let a lot go in sci-fi because I am not a scientist and am in no way qualified to nit-pick at the details, but the whole way in which the "apocalypse" had been contained, and that it was contained, just didn't make any sense to me. I also wasn't sure if this was another thing in which the "apocalypse," such as it was, had only effected the United States, as seems to be the case in many, many books of this genre.
I think that's about all there is to say with this one; I mean, it's very...meh. I don't think there's ever a big climax. The most "climactic" event happens probably midway through. Some people might have found the end, especially with Silo 1, surprising, but I've read another of Howey's books, Sand, which basically solves the same problem in the same way, so there wasn't really anything to turn my head there. In fact, the repetition actually disappointed me a little. I think Howey has some good ideas and some really creative settings and dilemmas, but I would have liked to see a different method of problem solving in the end here.
2.5 stars for this one; I enjoyed it, but only marginally more than it being "just okay."
