This was going to be a 5 star rating, but the book needed editing. There were a few grammatical errors that were easy to spot. Also took half a star for the misogyny. It didn't bother me too much because it was military guys being that way, and that's just the nature of them. My husband tells me stories of his buddies that would make my skin crawl if I knew it wasn't a joke.
Anyway, the plot was fast paced, the characters varied, and the settings well described. My recommendation is to not read Meg: Origins first, even though it's in the front of the book. Read the actual novel then go back and read the prequel. It gives things more suspense.
