Wool: A
A post-apocalyptic novel, "Wool" is the most engrossing thing I've read since "The Hunger Games"!
It's set in a huge, underground, 144-story, self-sufficient "Silo" where people have lived for countless generations after some forgotten apocalypse turned the surface of the Earth into a toxic wasteland.
It's very well-written, very character driven, very sociopolitical (in a good dramatic actiony kind of way), very gritty, very much a journey of discovery, and is both heartbreaking and heartwarming. I couldn't stop reading it - check it out!!
It turns out the author, Hugh Howey, is a self-made eBook success story - he built up a following by releasing the different parts of Wool as increasingly longer books on Kindle - "Book 1" was a neat short story and things snowballed from there.
