Though I'd classify it as "rated-R for extreme violence and sexual content," this book was one that was really thought-provoking, which is why I liked it. It's all based on the premise that a "cure" for aging has been discovered, and follows a perpetually-29-year-old's eighty year journey through his prolonged life. Telling the story of the "postmortal" world through one rather ordinary man was very effective. With him, the political, ecological, and social changes that came about really came alive and impacted the reader personally. Though I wouldn't necessarily call the protagonist a "hero," that wasn't necessarily a bad thing; it made the book seem more real and documentary-like, rather than a fantasy novel where the main character is (or believes himself to be) the one man to save the world.***SPOILER WARNING***I did think that the book ended a bit abruptly, but I suppose a nuke would have a tendency to do that.
