This is the third book in The Doyle Hawthorne Series. I have to say its just as good as the first two were. This series is a different approach to Zombies. More of a Scientific approach. This one leans more toward Chuck, where Doyle was mostly featured in the others. I haven't read too many books lately that make you want to skip ahead to see what happens. (I really wanted to know what Edgar told Addy) I hated to read the end of it because I know the next book isn't written yet. But one of the things I did like about the ending of this book was that it didn't leave you on a cliffhanger. I don't need a cliffhanger to want to read the next book. I can't wait to see what is in store for Addy, Doyle, Chuck & Kai.
