A well-written zombie apocalypse novel that is almost perfectly-crafted, but also kind of unmemorable, with few original things to add to the genre. It ends so abruptly and with so many plot points left unresolved that I had to look up whether there was a sequel. Also, and maybe this is just me, but like so many stories in this genre, I found it very depressing overall. The author seems to work hard to construct an utterly gray and hopeless world and make you feel that nothing will ever be redeemed. It was a very compelling airplane read, and I stayed up late to finish it, but the ending left me feeling very deflated.
