I only give it four instead of five star as it is only slightly not as good as the first (kill zone), but make no mistake Gunnery Sgt Jack Coughlin (experience and ideas probably) and Donald A. Davis(the guy who actually werites the book)are at the very top of this genre.
This book is non stop, non-put-downable and not so out there or unbelievable thanks probably to plenty of experience and research going into it. this book is totally worthy of a blockbuster film (i'm suprised the first which is epic! hasn't already been done).
BUY THIS! READ THIS! FOLLOW THE WHOLE AWESOME SERIES!!!
