Okay, so the good.
Overall the book was quite engaging and keeps you wanting more.
The twists, while mostly predictable, were well done.
My only real critique is the lack of knowledge of Firearms. There were so many inaccuracies spewed I thought I was listening to replayed preprogrammed propaganda/talking points of how guns works from someone who has done no research, or ever used one.
Again, overall loved the book, but I hate hearing BS about a subject that it is clear the Author has little to no Factual knowledge about.
