I was given a copy of this book by the author, Augustin Guerrero, in exchange for an honest review. This book is a sci fi/dystopian military story. To me equal to a man’s action movie, with a small touch of heart. Par for the coarse, there is some swearing, including the f-bomb with several variations. So if you find that offensive, delete a star. There was no sexual content besides some joking between the boys. So if you are guy who likes sci do or military stories, you’ll love it. Or if you are a woman like me who loves the comrade-ery and the whole “brothers in arms” “no man left behind” themes that can be found in military stories, you will enjoy it (if the language doesn’t get to you). I give it 4 stars due to my dislike for the swearing. I can only recommend it for adults due to the language.
