Wool was a complete surprise. A previously little-known writer creates a story, within a very popular genre (post-apocalyptic), that's completely unlike others. It grabbed me at once and just kept going. The best part is that there are 2 more books in the series: Shift & Dust. Originally written and released in small parts (within magazines), they were combined and released in a series of 3 larger books. I'll look forward to more from Howey.
