I'll start by staying that if you've read World War Z then your enjoy this book as well. They are both very different in that this book is more of a storyline but it firmly grips you by the arms and keeps you hooked!
I'm currently reading Part 2 of the Morningstar series, this book is Part 1 so you will need to buy the second book to follow on from this, but don't let that dishearten you as the storyline is great.
Ever movie/book has their own view of how a zombie should be, this book is no different, and to be honest the zombies have an interesting two sides to them... not going to give anything away your just have to read the book!
The read is easy and fluid while still holding a level of maturity that you will desire from any decent horror.
I would recommend this book (and the second) to any zombie fan - this book will not disappoint your need for a bit of zombie loving!
