My first book by the author and although is #4 in the series I could easily read it in a few hours and understand where everyone's coming from.

A fast-paced, suspenseful read that kept me wanting more and not stopping because I found the story very entrailing as there are so many issues that our society is still dealing with nowadays as it is PTSD and what happens with the retired soldiers.
The characters were reliable and the writing was very good as well.
i will make time to read the previous books as well for sure.
