Breakthrough (Breakthrough, #1)

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.

    A ripping high-tech political yarnFast-paced, well-written, interesting and scientifically sound political sci-fi.Good enough that I'm keen to read the rest of the series.A bit 'US rides in and saves the day', but it's hard to find any sci-fi these days that doesn't place the US at the...

    Entertaining and not badly written. There are a few plot holes, and some characters are thin. There are multiple protagonists, which is both good and bad: you have several story lines and some appealing people, but some get more time and explanation than others. The ending brings thing...

    A book written by a man who doesn't think highly of women. Two women in a large cast of characters. Both are portrayed as highly emotional, insecure, and needing help being heard. Men have dialogue showing they are surprised when the women are bright and comment on their appearance. th...

    Hey this author is great. He really moves the story along at a fast pace. The characters are well developed but you aren't bogged down with details as you are quickly moved back to the story line. Science fiction meets action meets environmental protection. It was a fun read. ...

    Exciting scenario Alison is working on getting computers ready to translate dolphin language into English, and vice-versa. This complicated project would enable humans and dolphins to speak to each other. A Trident class submarine moves 15 miles through the ocean in an instant, much to...

    Something old, Something new.I can remember the television show Flipper, in the 1960's . It was one of my favorite afternoon shows. Even then we knew that Dolphins were incredibly smart. I would hurry through my chores, and making promises to get my homework done before bedtime. That w...

    Brilliantly written. This is a book that brings wildest dreams to life, and something most humans have always wanted to do. Along with a dream coming to life, is the well rounded plot that includes action, interpersonal character growth and the complications of life. I highly recommend...

    This book made me fall in love with dolphins and despise part of the government for taking advantage, without consideration, of the hard work and amazing discoveries of marine biologist specialist. That's government for you. I'm not reviewing this story. There's already almost 2,000 re...
