Covert Threat is the fifth book in the Gray Ghost series. It mentions characters from previous books, but you can follow the story line without having to read them.
I think this is probably one of my favorites in this series. I loved the suspense build up. I enjoyed the equality of the mystery and romance. The romance part didn’t overtake the main story like in so many novels. Jules’ character was well written and I enjoyed following her story throughout the book.
I can’t write too much more without giving away the mystery. But, this book made a great rainy day read!
