This book contains the sort of material expected of Shaun Clarke. It is informative, fast, furious and basically on a higher level than many other authors in this collection. The only writer about the SAS that I can compare him to is Andy Mcnab DCM MM, who has written many brilliant factous books, and has recently started writing fiction. All of Shaun Clarke's books are a joy to read and include the type of information that is useful and enjoyable for any follower of the SAS no matter how big a fan they are.
