Catalyst (Breakthrough)

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.

In fact, seven in the last two weeks, all by different authors and all different types of fiction and writing styles.When I first started reading…

    Amazing! I discovered the Breakthrough series shortly after the first book was released. I was researching several genres relating to the genre that I write in (yes, I’m an author) and was, in two words, blown away. If the author’s name were withheld, and you asked me to guess who wrote it, I would be torn among Crichton, Ludlum, and Dan Brown, with something unique, and fun, and magical, and inspirational thrown it… and that part would be all Michael Grumley.It’s a page turner, folks…
