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!

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!

I'm hooked.<br />

I began reading this series because the author had the good sense to use Scott Brick as the narrator. I'm anxious for the Audible release of the next book, Ripple. The story is fascinating and definitely one that you will read non-stop as much as possible. The author likes to keep up to four plotlines going at once, so you have to learn who everybody is, like a Russian novel. There's a cliffhanger at the end of each chapter.

Excellent reading and superbly narrated

I am a physician and always loved science, including science fiction that certainly falls within the realm of future possibility.
Great storyline that further validates that we are not only a speck in the universe, but there is so much we do not know.
I am going on to book 4 now And I only hope that Mr. Grumley keeps writing . Wish the new book was an audiobook, but I’m sure that’s coming.
I listen to a lot of audiobooks, and I can only say that Scott Brick ranks in my book as one of the best narrators I have listened to

Can’t wait for the next installment

Found the series by accident. So glad I did. Great story line and Scott Brick is a wonderful narrator.

another enthralling addition to the series

if Breakthrough and Leap helped me through the tediousness my daily commute (thanks to to the narration by Scot Brick and a great premise by Grumley and his characterisations of the cast - Catalyst ruined my sleep patterns. Again for mostly the same reasons, and I wanted to regularly check to see if Steve Ceasar wasn't creeping in the rhododendrons outside my windows.

Grumley has done the scifi community a service by verbalising the thoughts in the debate over interpretation, genetic origin, and intelligent design. The cross species link between human and other animals is mostly explored in either the magical realm from the fantasy genre or in the assumed tech of far future tech of scifi. Here in this near future scifi it is stretched (through the growing pains and computer glitches) to plausible dimensions, and humans are by no means going to take the center stage. I enjoyed the plot and character development where the good guys are almost too good (hey and why not have a really good hero here?) the bad guys? they are just dripping concentrated evil! Great pace to the plot development too! Catalyst has all the elements of a great escape onto the peaks of South America to submerged vessel in the Caribbean, from the Pentagon boardrooms to the enclaves of modern China, and to the romance (and why should scifi be all science and have no lovey-dovey?) for our almost too good Alison, Sally and Dee-Anne.

As in the previous narrations by Scott Brick, the text really came alive and his range of accents has really elevated a good story to prized keep sake. I will forever keep his rendition of evil Oterra in mind when future literature comparisons are made.

I'm really going to prune those plants back (and take a microscope sample tonight) - nothing natural should have leaves that regenerate so darn fast?

Makes you think

I enjoy learning scientific terminology while listening to the story. It’s fast paced and 3 different scenes happening at the same time really keep the reader/listener engaged. I’m going to order the next one, Ripple, now!! Please keep writing!
