5 Stars.
Give this book a good ten chapters. After that, you'll start to like the main character, Arliss Cutter. From there, your interest in the story will grow. And, by the end of the book, you'll enjoy Cutter so much that you'll be ready to read book #2 in the series.
No vulgarity or sex scenes. There are mid-level cuss words littered here and there, but overall a fairly clean read. I really liked that. Most foul language does nothing for a good, well-written story.
Open Carry had a good balance between action scenes and all the talky-talk that's necessary to further the plot. I'm not sure why, but my mind was taken back to David Baldacci's King and Maxwell series, as I read this book. And I loved those novels.
Having read a couple of Cameron's Jericho Quinn books, I'm very impressed with his work.
This author highly recommends Open Carry for fans of action thrillers.
