Wow... I loved this story. It had history, thrilling cave dives, an ocean cruise liner intrigue, archeology, black market, and the main protagonist on this one was Mallory. If you are familiar with the series, husband and wife team, Alton and Mallory Blackwell, work together, but Mallory took the lead in this story. I rather liked that. The history the author used was terrific and reminded me of Dan Brown. Steve Freeman has his own style, and it was dramatic in this book. You won't want to put it down, and if you are a new reader he brings you into the fold.
The characters were complex and each has their own foils which only adds to the suspense. The descriptions of the area and of the archeology dig were terrific! When the cave diving came into the story, that added to the suspense and thrill. Another great job!
