I don't really know what to make of this book. Firstly, it's very short, which made it difficult for me to really get into it. Secondly, the dialogue is quite scarce, so the characterization of the protagonists is rather sketchy. Even the plot is very bare and while you wonder what's going on, the main theme is rather how people react to the crisis, what they say, what they do, than about what caused the crisis. I can't say I didn't like it, and I liked it much better after a second read, but compared to the other novels by Don DeLillo that I've read, it's different. So if you want to get to know this author, I'd rather recommend "White Noise" or, if you're feeling brave, the monumental "Underworld".
