This was a good "post-oil" world scenario thriller. I didn't exactly agree with the author's political views in the book, so as a result, this book received 3 stars.
Otherwise, the story had a good pace and believable after-effects on the world after "peak oil".
So, I guess I would be reading the sequel Afterlight sometime in the future. And it being a post-apocalyptic novel (my favorite sub-genre), I am quite excited to read it whenever I get my hands on it.
