This is quite simply one of the best books I have ever read. It contains everything: romance, action, sadness, mystery… Don't think twice about reading it. If you're on this page, go and read it now!
I wouldn't recommend it for anyone under 12 as it does contain scenes which may be inappropriate, but for anyone else, it's a brilliant read. Malorie Blackman is excellent at capturing every thought and feeling of the characters, and the plot will have you in suspense for the whole book.
