To me, it deserves 5 stars, but to some other readers it may be just horribly horrible. The plot is extremely confusing and the reader may just stop wanting to read the book once they're into the first chapter. However, to those who find it interesting, they may want to keep reading because of all the unexpectble things that always seem to happen to the people who are the last members of the human race. All I want to know is what will become of those people, and how Applegate will conclude the series.
