Publisher's Summary

With sweating hands, Alison Shaw stared nervously into the giant seawater tank. One year ago, she and her team of marine biologists had stunned the world with an incredible breakthrough. Now they were about to do it again. And this time, they were ready.
But an ocean away, something strange was unfolding. Along a lonely coast in South America, an experimental Russian submarine - long thought to have been dismantled - has suddenly resurfaced. And the US Navy has taken notice, sending John Clay and Steve Caesare to investigate.
They discover the sub has been quietly studying a group of soldiers making mysterious trips into the jungle under the cover of darkness. The group has discovered something...something big.
And what Clay and Caesare uncover next is the last thing anyone expects. The discovery of the century has been made...and someone is ready to fight for it.

Utterly fascinating contemporary science fiction!

Leap is Book 2 in the three book Breakthrough series. Book 3, Catalyst, is scheduled for release on June 14, 2016, but the audiobook will likely come later. This Leap audiobook includes approximately one hour of Catalyst.

The Breakthrough is about scientific breakthroughs coming from the efforts of several scientists and their teams. I will not give more away than that. It is a wonderful action series that is totally appropriate for all ages beginning as young as 7 or 8 years old. The series could easily be marketed as YA science fiction.

Michael C Grumley may well be destined for becoming a great author of fiction.

Leap and the Breakthrough series has my highest possible recommendation. The series reminds me somewhat vaguely of Hunger Games series and Divergent series, but without the prior apocalyptic events.

- Wayne "I love espionage, legal, and detective thrillers but listen to most genres. Very frequent reviews. No plot spoilers! Please excuse my typos!"

Good story and well written.

I cannot imagine why this has to be self published. The publishing houses who rejected this book should be ashamed. It is entertaining. The characters are sufficiently well developed. It hits well on all marks.
