This was interesting - basically a woman makes a decision that leads to an accident, and you see the repercussions of that on the lives of other strangers. So it kind of felt like a collection of short stories that were interconnected. Some chapters were better then others, though I didn't particularly like any of the characters. It also felt very small (which isn't necessarily a bad thing), but I guess I had higher expectations since this came highly recommended. In a way, it might have worked better as just the first chapter. I also don't really get why the book is called "improvement" - I mean I get they're all trying to improve themselves - but I don't think the title really makes sense for what this book is about.
