Slightly off-topic, but I'd like to recommend the Silo Series also by the author of this blog post. They're perhaps not life-altering in content, but enjoyable sci-fi reads, nonetheless.
Howey is perhaps my favorite new(ish) sci-fi author. His novels are almost always page turners, even if they aren't always deep. Wool (book one of the Silo series) was my introduction to Howey, and also among his best. I also recommend it for anyone that likes post-apocalyptic sci fi. Sand is good, too.
