Deadly Plunge is the sequel to Last of the Seals which I reviewed back in July 2012. I'm always a little wary of the second in a series, especially if I really enjoyed the first one. I'm afraid of being disappointed. I am happy to say that I enjoyed this book as much as the first. The book was well written and full of adventure. The story sucks you in and doesn't let go. This time around, Sam and his girlfriend Amelia get sucked into a mystery that includes kidnapping, murder and international espionage. Along with the mystery, we get to see more of Amelia and Sam's relationship. Their love is growing stronger and big changes are coming. 
 One of the great things about this book is that it really takes you back to a completely different way of living. Television shows weren't on 24/7. Women were grieving because Elvis was drafted and stewardesses were victims of discrimination. My 2013 brain can't wrap itself around the fact that women couldn't marry or be engaged and had to have certain looks and measurements in order to work for the airline. They would never get away with that nowadays. Sprinkled throughout the book, the author has included photos of real life places and historical events that have been included in the story. That was a really nice addition and really enhanced the story. 
 Sam and Amelia's adventures continues in the next book, San Francisco Secrets, which comes out Spring 2013. I can't wait!
