A reader should be warned that this book has a few derogatory words in it, but not awful enough to downplay the excitement of the plot. They are easy to overlook, but the author could have left out many of them without changing the story. Orion, who is the main character, is forced to be brave and fearless in this whirlwind of adventure. Once the crew is compelled to try and survive on a rough and harsh terrain, it takes every ounce of bravery to stay alive. Mysterious things begin to occur and sadly, a few men meet death. Boys ages 11-13 would enjoy this book most. As a girl, the blood and gore was a distraction to the plot. Setting aside the critical and slightly offensive words, this book will definitely capture your attention with cliff-hangers, action, excitement, and more!
