**ONE OF THE GREATEST ACHIEVEMENTS IN HUMAN HISTORY.** **A SECRET THAT WAS NEVER SUPPOSED TO BE FOUND.** **AND A CRISIS THAT CANNOT BE STOPPED.**
Deep in the Caribbean Sea, a nuclear submarine is forced to suddenly abort its mission under mysterious circumstances. Strange facts begin to emerge that lead naval investigator, John Clay, to a small group of marine biologists who are quietly on the verge of making history.
With the help of a powerful computer system, Alison Shaw and her team are preparing to translate the first two-way conversation with the planet's second smartest species. But the team discovers much more from their dolphins than they ever expected when a secret object is revealed on the ocean floor. One that was never supposed to be found.
Alison was sure she would never trust the military again. However, when an unknown group immediately becomes interested in her work, Alison realizes John Clay may be the only person she *can* trust. Together they must piece together a dangerous puzzle, and the most frightening piece, is the trembling in Antarctica.
To make matters worse, someone from the inside is trying to stop them. Now time is running out...and our understanding of the world is about to change forever.

### Review
***"If you like Clive Cussler you will love this book!" - Gail Ward***
*"You'll miss a great experience if you don't read this book." - J. Schilling*
***"As a Clancy fan and a former submariner I thought I was buying a techno thriller. The book stands alone. A great read with lots of interesting and thought provoking events. I looked forward to each chapter and the ride it provided. Well done!" - Robert Clark***
*"After I finished "Breakthrough" at 11pm in bed I immediately bought his next book; "Amid The Shadows" without even reading the synopsis or the reviews. I just wanted more good story." - K.A. Higgins*
***"Right up there with Michael Crichton. Wow - where did this guy come from? Being retired and having read several hundred Kindle books, I can honestly say this has to be the most exciting heart pounding story I have yet read on my Kindle. I give it 10 stars out of 5 and - as another reviewer said "I guarantee you'll be downloading his next book.... The minute you finish this one." I sure did." - L. Spaiser***
*"This story was impossible to put down. The technology was fascinating and believable, the plot complicated enough to keep me interested and the characters were real. I was there, in the cold of Antarctica, felt the bullets whizzing by in the aquarium, and in general had a great adventure. As a postscript, I finished the book, found that the author had another Amazon book available, Amid the Shadows, and immediately downloaded it. I can't wait to jump back onto Grumley's bus!" - Shelley Morgan*
***"Better than Dean Koontz. Five stars. I expect great things from Mr. Grumley and am looking for his next book. Five Stars!" - Sandra Rocha***
