I have read some awesome books lately. I just finished The Compound, and I would highly recommend it. I'll warn you, though, it does get a little disturbing. It's about a multi-billionaire who builds a huge underground compound with living quarters, medical facilities, a livestock area, and even a church chapel. Why would he do this? Well, he is worried that a nuclear war may break out at some point, and he wants a place for his family to stay - for fifteen years! That's how long there would still be toxic levels of radiation in the air.
And that, my friends, is all I am going to tell you because to tell you more would ruin the surprises in the story. Trust me, though, this is indeed an awesome read.
