GRAVITY WARS SERIES

Interstellar Assault (Book 1)

There are no light sabers, telepathy or warp drives here. No hyperspace or jump points, either, just the hardest science we know to show how space war might really take place.

A beaten race flees the terrible Vims in a generational vessel, working year after year to reach relativistic speeds as the passengers search for a new star system.

The Vims launch three interstellar missiles. It might take 300 years for the missiles to reach the generational vessel, but the relentless chase across deep space has begun.

This is the story of the heroic Sargon, his granddaughter Ningal and her son Assur as they face mutiny, scientific evil, and the despair of a seemingly doomed voyage. It is also the tale of James Petty, one of the most powerful CEOs of 2060 Earth, and Colonel Mike Steele leading humanity’s first space marines in an experimental Orion ship—using nuclear bombs for propulsion.

INTERSTELLAR ASSAULT is the thrilling first book in the GRAVITY WARS series, a hard science fiction saga of flesh, blood, boldness and action, and of alien invasion and human courage spanning many generations, written by bestselling author Vaughn Heppner.

Saturn Protocol (Book 2)

There are no light sabers, telepathy or warp drives here. No hyperspace or jump points, either, just the hardest science we know to show how space war might really take place.

The aliens on Titan are building a gigantic 200-kilometer railgun to launch devastating projectiles at Earth. Each mass-produced meteor will hit with the kinetic force of a nuclear bomb, destroying one targeted factory at a time.

Humanity must destroy that railgun.

The problem: any decision will take years to implement. A wrong choice now can mean bitter defeat later in the ultimate Darwinian game of 4-D chess.

Earth begins assembling 100,000-ton Orion ships, vessels that use nuclear bombs for propulsion. How many are needed to win at Saturn? The journey will take one year. Time is ticking on the decision.

As an afterthought, four stealth ships are launched. They will take three years to reach Saturn. Surely, the war will be over by then.

Nothing could be further from the truth.

SATURN PROTOCOL is the second book in the GRAVITY WARS series, written by bestselling author Vaughn Heppner.

Nova Strike (Book 3)

There are no light sabers, telepathy or warp drives here. No hyperspace or jump points, either, just the hardest science we know to show how space war might really take place.

In 2074, aliens arrive on the Moon’s dark side, sending assault landers and space marines to capture the near side. Their plan: install kilometer-long mass drivers to hammer humanity into submission with lunar rocks.

The rain of death from the Heavens means the end of Earth. The aliens will win, and who knows what they plan for the masses.

Earth’s nearly paralyzed leaders hatch a desperate response. Use missiles to cover the crash-landing of a team of elite commandos and an experimental nitrogen-powered craft on the Moon.

John Steele is their leader, leaving behind his wife and kids for the good of the human race, trying to stop the aliens in the longest deep raid in the history of Earth.

NOVA STRIKE is the third book in the GRAVITY WARS series, written by bestselling author Vaughn Heppner.

Extinction Orbit (Book 4)

There are no light sabers, telepathy or warp drives here. No hyperspace or jump points, either, just the hardest science we know to show how space war might really take place.

This is it: the genocide campaign. Chief Marshal Assur wants it all, victory over Earth and immorality for the Valiants.

The plan is brutally simple. Some call it the Dinosaur Initiative. Crash three asteroids into the planet, wiping out the human race the way most of the king dinosaurs perished eons ago.

The Valiants will guide the powered asteroids all the way to Earth with their new and improved fleet.

Those of Earth must put aside their differences and build a fleet big enough to challenge the Valiants and stop the asteroids. If they fail, it’s game over for the human race.

The plans are simple: the fighting will be everything.

EXTINCTION ORBIT is the fourth book in the GRAVITY WARS series, written by bestselling author Vaughn Heppner.
