Gravity Wars: Interstellar Assault

Rate this book
With their homeworld a radioactive ruin due to alien bombardment, the last hope of a beaten race is the Voyager Akkad. It’s a vast, generational vessel with a magnetic ram scoop, working year after year to reach relativistic speeds as the passengers search for a new star system to colonize.

Then marauding Vims in the old system spot the Akkad and launch three interstellar missiles. It might take 300 years for the missiles to reach the ship, 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 munity, 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 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.

I was born in Canada and remember as a small boy crawling in my snow-fort. I closed my eyes, and when I tried to open them, they were frozen shut. I didn't panic, but wiped away the ice crystals, unglued my eyes and kept on building my tunnel. Those were great days! I moved to Central California before seventh grade and couldn't believe I lived in a land where oranges grew on trees and you could pick grapes from the vine.

I used to wonder what I wanted to do with my life, what kind of work specifically. I was miserable not knowing and bordering on desperate. Then one day a friend gave me his typewriter. I began working on a novel. A different person told me it was much easier on a computer, so I bought one and began getting up at 4:30 A.M. each morning before work, writing for three hours. My eyes were unglued once again as the pang of misery left my gut. I knew exactly what I wanted to do: write. So now that's what I do, I write, and write, and write, and I love it.

A fun read

I hope this series continues. The story started slow, but the second half is great. The realistic space flight timelines are a nice change.

Very good

A great story with believable characters. I would be more than happy to read a whole series about the Valiants and the earthlings and see how they have a common ancestor.

your best, in my opinion

I’ve become addicted to the series you have. The one with star watch, and all the different characters. But it’s gotten stale lately. This is a fresh start.
