This book, like the first, is written in diary form. I normally hate diary form fiction, especially in zombie books, but this author has the handle on writing in this style. Actually, this author writes in a unique style that had me laughing at times from the slang and nicknames used. The subject is pretty serious, though, and the author conveys that gravity in the descriptions of the world and the horrors inhabiting it.
Without giving any spoilers, I just wanted to comment that one of the cool things about this series so far is the unpredictable nature of the plot, and how things can zigzag on you with little notice. Sort of like real life, which is scary enough sometimes without the restless dead. I enjoyed the new characters and I still want to find out more about Apocalypse Girl. The ambiguous nature of her relationship with the narrator is driving me crazy, but in a good way.
