Publisher's Summary

All secrets are eventually revealed, given enough time, decades or even centuries. But one of the greatest secrets of all took only one small and unexpected discovery.
Facing the cold, clear glass, Alison Shaw stared nervously into the giant seawater tank.
It was just one year ago that she and her team of marine biologists had stunned the world with their incredible breakthrough. And now, they were about to do it again.
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 had taken notice, sending officers John Clay and Steve Caesare to investigate.
The sub has been studying a group of unmarked soldiers disappearing into the jungle each night, beneath the cover of darkness. Something has been discovered - something big.
And unfortunately, the soldiers are about to learn that making the find of the century is one thing. Keeping it, is another.

Breakthrough continues... excellent sequel!

So this sequel to Breakthrough is just as good. In this book there is a Chinese war ship in Guyana along with heavy moving equipment, trucks and men who go into the jungle at night. The government has told locals they must not go anywhere near the area at night.
At the same time in Brazil a preservation for animals (especially those rescued from pharmaceutical labs) has been attacked leaving many of the animals dead and the man who cares for the abducted. By who, no one knows. Allison is still working with Dirk and Sally while her coworker DeeAnn is working with gorillas using similar equipment to communicate. The man who disappeared from the animal preservation (Luke) was her mentor. The owner of the preservation believes that a capuchin monkey may hold the key but first they must find the monkey and then they must try to communicate with it. The monkey, if not dead is hiding somewhere in the thousands of acres belonging to the preservation. For some reason DeeAnn doesn't quite trust him, is he really a philanthropic old man or does he have a hidden agenda?
What the heck does this have to do with the Chinese people? Guess you'll have to read it to find out!
You don't have to but I would suggest that you read the first book (Breakthrough) before reading this book. It kind of gives you a feel for the characters as well as background on their relationships that is not fully explained in this book. There are also characters that appear towards the end that you will be lost about their identity and abilities without having read book one.
With the incredible voice of Scott Brick narrating this book sounds perfectly believable.
HIGHLY RECOMMENDED.

More amazing as the tale continues

Michael Grumley has outdone himself once again. I completely fell in love with the lead characters in Breakthrough and in Leap they are even more well developed. There's also a few new players in the game that have stolen my heart and have my full attention. This is an absolute MUST read and from the first page until the last you'll be on the edge of your seat. Scott Brick also does an amazing job bringing this story too life and I can't wait for Catalyst and the rest of the series to continue!!!
