Princess Grace of Earth by A K Lambert

Fleeing the threat of civil war on her own world and a planetary genocide game played by an ancient and evil race, Princess Grace and her small band of refugees seek sanctuary on distant Earth.

But their peaceful existence is shattered when one of her own betrays them.
With Earth hanging in the balance, an unlikely hero comes forward to challenge the impossible odds.

“A must read for any Sci-fi adventure enthusiast. I enjoyed the mix of all the different characters and the locations. It’s one of those books that gets harder to put down the more you read.” Amazon Reviewer
