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.

Hooked

I have enjoyed listening to this series very much. I was just wanting something to listen to while working. I have been hooked since listening to the first book 3 days ago and I have now just finished the 3rd book and getting ready to start the 4th. The storyline is outstanding, the characters are engaging and the author has made me cry because of a sad scene. When an author can do that then I classify them as an exceptional writer who can engage the readers imagination and emotions at the same time.

Not as good as the first two.

Even though I plan on seeing the series to the end; I felt that this wasn't a strong enough entry. The real progression of the overall story doesn't take place until the very end, last few minutes. However, with the revelation at the end, I expect the next book to have more substance.

Wildly Satisfying

The story is equipped with several developing frontiers allowing for complexity of character and emotion. It offers easy listening and yet draws one back for a steady diet of intrigue.

Audible quality was poor. Loved the story

Very poor Audible recording. The reader almost sounded like a robot or other non human reader. The book is as good as the others in the series. I will not plan on purchasing the Audible version again.
