I have been fortunate to have read everything written by this author. I remember, while reading this book, that my first thought was "Again, the author has shown that he can write with the best of them".
We have the same cast of characters in this book as in the previous ones so it would be a bit helpful for the reader to read them in order but not absolutely necessary. There is a departure from the marine theme of the previous books. That was a risk due to the author's background in the maritime industry. A risk that paid off. I believe this story is a logical extension of the previous books.
R.E. McDermott is a genuine top tier author that has crafted a good cast of characters for his stories. I am enthusiastically waiting for his next installment. I highly recommend his books to anyone especially thriller fans.
