I thought Hugh Howey's Wool series was amazing. The Sand series is just pretty good. The character development was great - I loved the family, and the various members. He did a great job of fleshing them out, and making us really care about them. That was my favorite part.

But the world... as a post-apocalyptic world, it just doesn't have the dimensionality, interest or believability that I expected, or that he pulled off in Wool. Some aspects of it didn't quite make a lot of sense to me. (Frankly, Denver, Colorado below hundreds of feet of sand is pretty darned far fetched, even given his explanation - and if so, getting water would be much more difficult than he suggests.) Although the idea of sand diving is pretty cool.

Anyway, I did enjoy reading it, but it's not up to the same as his other work.
