I liked book 3 a lot more than book 2 (thankfully, because I was worried it was gonna go downhill from there). It's action-packed and exciting and I didn't want to put it down, whereas with book 2 I could take it or leave it. Most of this book is spent away from the prison (whereas book 2 was contained almost entirely in the prison, which became monotonous and boring and started to feel like a zombie-age soap opera since it revolved around drama between different people in the group). Since they get out and about, there's a lot more carnage and zombie battles which is fun and reminds the reader what an awful and terrifying situation these people are in - everyone was becoming too placid and comfortable in the last book in my opinion. Also, it kind of looks like there might be an impending war between the main characters and another band of survivors, so that will be interesting.
