Publisher's Summary

In 1984 a doomsday vault was constructed on a remote island in the Arctic Ocean. Its purpose was to preserve Earth's genetic history in the event of a global catastrophe. Now, decades later, a second vault has been uncovered. This one resting where no one ever expected. And the problem is, it's not ours. 

Yet even more curious than the vault itself is what lies inside. Seeds. Millions of seeds. Each with a genetic embryo untouched and perfectly preserved. Waiting. No one knows who built it. Or when. 

What we have managed to figure out is that whoever it was traveled an immense distance. For the sole purpose of hiding their genetic blueprints on Earth. But why? 

Now a small group of marine biologists and navy investigators have been assigned to find out. Before anyone else does. But Alison Shaw and John Clay are not prepared for what they are about to uncover. Beginning with the truth behind our own evolution.

This series just keeps getting better and better!

Strongly recommend this book series. Once you read the first book, "Breakthrough", you may want to have each subsequent book available on your Kindle or audiobooks, or as a hard copy, because you will want to keep reading! These books, which are sequential, will attract anyone who enjoys intelligent, well written novels, with a dose of science, interspecies communication, military operations (with Navy SEALs!), a touch of romance, and of course, implications regarding alien civilizations. You will not regret getting hooked on this "Breakthrough" series!

Sci-fi action and adventure...

Catalyst is a very good addition to the BREAKTHROUGH series. I must caution any new listeners to this series, although each new book has it's own unique plot, each book uses events and information from the previous books to add dimension to the new book. Relationships between characters also builds from one to the next.
In this book the protagonists are trying to keep what amounts to the fountain of youth (only on plant form) locked away from human reach. The people who are after it are not morally or ethically people who would use it's healing abilities for human good but rather for their own gain.
This book has an abrupt ending and leaves you with a major cliffhanger and an introduction to the next book in the series (RIPPLE).
Interesting, far fetched and thoroughly entertaining.
Scott Brick as always does an outstanding job narrating.
HIGHLY RECOMMENDED

MUST READ!!

The Breakthrough series has left me wanting more, and Catalyst was no exception!! My favorite so far, Catalyst was fast paced and intriguing...I couldn’t stop listening!! Scott Brick never disappoints with his delivery, and adds another dimension to the listening experience! This series doesn’t disappoint!

Breakthrough Series Highly Recommended

A thoroughly enjoyable series even if you are not typically a fan of the genre. Never heard of the author but took a chance when Book 1 was on sale and I am really glad I did. Listened to all 3 books in the series, really need to do in sequence to be able follow the plot and character development. The first book in particular has plenty of new subplots, which follow through en each book and tie together nicely. I hope Book 4 Ripple will be available on Audible soon!

Utterly Addictive Series

Make no mistake, this is one of the best techno thriller/suspense series in recent memory... Inter species communication complete w/ talking dolphins and apes, alien contact, superb military spec ops, scientific exploration, geo political issues, and so much more... Freight train plot and edge of your seat adventure... I bought each next book in the series before halfway through its predecessor.. Chills and humor in equal measure... As the series continues I see more of a David Brin homage;). I read all 3 installments in significantly less than a week... Simply impossible to put down such riveting fare;). My only complaint is the wait for the next one, Ripple, and the ending on this one makes the prospect of that one more than tantalizing...Particularly enjoy the idea of rediscovering communication abilities we have somehow lost as we evolved, and the presentation of the other sentients having not lost same... We need that fancy IMIS ai linguistic exploration to rediscover what we’ve lost.... I can see the IMIS eventually showing those same sentient signs in short order given how fast the learning is progressing w/ the aid of Dirk, Sally, and Dulce... Narration as usual is superb....

Best New Series

This is one of the best new series that I have came across in a long time. The author has done an outstanding job in the creation of his story line. It is completely different from most science fiction stories. One feel that this could be a true story even though you know it is fiction. Hope that Audible hurries up with book 4 of this series. By the way, it is a listen that you can hardly put down once you start.

Wow, even better than the first two

I really enjoyed the first two books in the series. I was constantly captivated by the surprising twist and turns that I never expected or saw coming. While I was looking forward to this next chapter, I didn't expect so much suspense and mystery. There's a lot of refreshing ideas and unique takes on story that mixes with real world current day events. This was a really stellar read and has me chomping at the bit for the next book to come out. I can't wait to find out what happens next!
