The Children of Men, by PD James

We saw the movie a few weeks ago and really liked it (minus a few flaws, of course) and I was really eager to read it. It was a wonderful book, and they did an excellent job of achieving the tone of it in the movie. Some of the plot points and character conflations I wish had been handled differently. The fact that Theo (in the book) killed his own child accidentally, for instance, goes so far to explaining how morose he is. Anyway, very dark and creepy and it does make you think.
