I like this book because it was talking about the military and it was talking about dogs. I love dogs and I like the military or talking about how man's best friend goes to war. Corporal Dempsey and Gus the military dog are working together in Afghanistan .Loki was sniffing out traps and booby traps so they wouldn't hurt the Marines or themselves themselves. I am 11 years old and I recommend this book to kids my age. I loved this book. It related to me in so many ways. Plus it's about dogs mixed with some suspense and action. This book was about a guy named Gus who wanted to be a dog handler in the marine corps. So as the story went on he met his partner Loki. Loki was a black playful lab that has been in the marine corps for years. So this book made me relate because I have a dog that acts like Loki, but she is not a bomb sniffing dog. Also this book is about the recent war in Afghanistan. I loved this book and I hope you will read it too and enjoy as much as I do. If you liked this book then there are three more books in the series.
