It began with a breakthrough. In interspecies communication. Leading both John Clay and Alison Shaw through a series of startling discoveries and life-altering revelations. Divulging who we really are as a species. Why we are here...and who is here with us.

And the greatest lesson of all, that our brains are not as rare and unique as humans had assumed. But rather just one of three brains between three extraordinary species. All influenced by a fluke of evolution that should never have existed on Earth in the first place. Something we are now finally on the cusp of understanding.

It will take more than just one brain to do it. More than just one species. And courage from all three.

Courage in the face of those still trying to stop Clay and Alison before their stranglehold on the world is lost.

But Clay and his team already know the truth. That there is no courage without fear, and no victory without sacrifice.

Scott Brick'snarraton is perfect for Michael C. Grumley's BREAKTHROUGH series. I can only think of the word Renaissance to categorize this and the other novels I this series. The main characters are likable and developed. The novels contain a wealth of historical knowledge and a hope for humankind to evolve and coexist with nature and other species. There is also the possibility of there being other life forms in the universe. I also loved his sense of spirituality woven in the novels. Best series to which I've listened. Couldn't stop listening, yet sad to finish.

Thought provoking ending to a wonderful series

I love Michael's writing! As always there is just the right amount of science, Sci-fi, technology and mysticism to keep you on your toes for what us possible now and what may be in the near future.
In addition, his characters have real relationships that are rich and varied. ECHO is another great novel excellently written and the audiobook is superbly performed by Scott Brick. My only disappointment was that Dulce and Dexter didn't have bigger story lines in this book!

As always a superb book!

Just finished the last book of the Breakthrough series and wished there were more books in the series. I got so involved with the characters and was on the edge of my seat with all the books!!! More..more…

I liked checking in each day to see what was happening next with the very likable characters that remind me of the 80's .

Really enjoyed story

With the search for the Lost Ark, this book reminds me of some of James Rollins' books. The characters are well written and the story flows at a rapid pace. I was a little surprised at how little DeeAnn Draper and her apes, Dulce and Dexter, were included in this book but I thought there was plenty of action without them. I like the whole concept of this series involving humans learning to communicate with other species and thought it was really well handled. I have to admit that I am sorry to see this series end (at least I assume this was the end) but look forward to other books from this author.
One negative comment: I feel like the narrator, Scott Brick, a very experienced narrator, was far too emotionally "over the top" in his narration. At times I felt like I was listening to a soap opera rather than an action novel.

A Terrific Conclusion to the Series

What a phenomenal series!!! Everything about these books are amazing! The links between everything leaves you questioning reality and what else is out there and how we became to be.

Thank Michael for the entertainment and thought provoking literature!

Ooooh the last line.

I’ve read Michael Grumley since his first book and had contact with him about the dolphins. Being from Florida I grew up in the tropical waters and often entertained by the dolphins as they would swim along the sides of the boat.
You could always feel them. My dad was Native American with a ‘sixth’ sense with humans and animals alike maybe I inherited some of it.
Able to “speak” the language of most animals esp

Interesting as always
