Publisher's Summary

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.

    "Grumley could be the new Crichton!!!!!"
    Any additional comments?

    This was so good, I really enjoyed this book. If you're looking for a fun and fast paced sci fi that is reminiscent of Michael Crichton's SPHERE then this is the book for you. <br/>In this book a couple of researchers have developed a computer program that has decoded the sounds of dolphins and can translate them to speech. In steps the Navy wanting to use the dolphins and give them instructions to find lost equipment on the bottom of the ocean. The dolphins find it but they also find something else-some kind of portal. It's either a gateway or a source of energy but it is not of this world or so it seems. There is also a city with 1,200 beings living there. Are they people ? humans? friendly? Or not? Should the Navy shoot first and ask questions later? <br/><br/>Scott Brick is as always a fantastic narrator!<br/><br/>HIGHLY RECOMMENDED. <br/>If you found this review helpful please indicate so. <br/>Thank You.

    "Enjoyed every minute of this"

    This was so satisfying that I can't accept that it was over. I was hooked from the first few minutes and never lost the feeling. I simply could not stop listening. The writing as well as the story was very gripping.

    Scott Brick is as always superb in his performance.

    I would give it 10 stars if it was possible. I'd highly recommend this book to everyone I come across. I can't wait for the next book in the series.

    "AMAZING!!!"

    I listened to this book and couldn't stop. Every single break at work, every moment in the gym, every ride in the car this book was playing. The writing was phenomenal and the mind blowing plot had me hooked. I CAN'T WAIT to read LEAP and the rest of the series. I do wonder how much of this was science and how much was pure fiction. Either way I was thoroughly entertained and intrigued.

    Any additional comments?

    This book is well worth a credit. Scott Brick is amazing as usual and the story is pretty cool. Being a software developer I was happy the technology discussions didn't insult me. Dolphins are amazing animals and I don't think we yet understand how intelligent they are. It's been proven dolphins call each other by unique sounds/names how much further advanced are they? Well that's the fun part of the story!

    The temple was thrilling, then a ration was perfect, the characters or believable, and it was a story that was impossible to put down.
