Wool (Silo #1)

A very strong start. The first half in particular, where we were limited to a single point of view. I found the protagonists to be sympathetic and interesting. And the mystery was very... mysterious. An excellent piece of worldbuilding. As the story progressed, and more POVs were introduced, and more action, I found the tale weakened quite a bit. Not so much that I'd shy away from continuing books in the series, but I'm also not rushing out.
