An excellent conclusion to the series. The concerns I had at the end of book two, that something had happened that was completely unbelievable, turned out to be false, and satisfied in a very interesting way.
This book had lots more zombie action than previous books, but at heart its a political conspiracy theory kind of book. One of my favorite quotes was,
"The problem with people who have power is that they start thinking about what it takes to keep that power than they do about what's right or wrong or just plain a bad idea".
The only problem that I had with the book, and hence the 4 stars instead of the 5, was that I never felt completely drawn into the characters' world. I felt like I was reading their blogs instead of standing in their shoes.
