Product description

Product Description

Damn aliens. Always trying to conquer the galaxy!

From international bestselling science fiction author T.R. Harris comes the 22nd volume in his Epic 29-book-long Saga of Human Superiority throughout the galaxy, and the foolish aliens who get in our way: 
The Human Chronicles Saga - Force of Gravity

A fleet of invincible starships. Millions of killer robots. Hundreds of worlds falling to the alien horde. And a sinister mastermind behind it all.

Just another day in the life of Adam Cain - the Alien with an Attitude.

As the evil Klin continue their rampage across the galaxy, Adam enlists the help of mutants Panur and Lila to find a solution to the Klin problem.  But time is running out. The deadly power of the Klin is growing exponentially with each passing day. And add to that the sniveling politicians from the Expansion and the Union who fear Adam's daughter Lila more than they do the Klin.
Now Adam is up against enemies on both sides of the conflict, leaving it up to him and his team to save the galaxy--again. But this time he has some major brain-power on his side. It all leads to an incredible roller coaster ride of twists and surprises along with the non-stop action and acid wit you've come to expect from Adam Cain and his eclectic mix of heroes.
The adventure continues with another page-turner. So pull the shades, lock the door and put out the Do-Not-Disturb sign. Adam Cain is at it again.

The Human Chronicles Saga is a MUST-READ for all fans of action-packed science fiction. Now 23 books long, the series continues--and will--as long as there are forces out there looking to cause trouble in the galaxy.
Pick up the entire series today ... and find out why this thrill-a-minute collection of space opera/military adventures has been one of the bestselling sci-fi series on Amazon for six years running.
