King Grim Vasteri is the most powerful and dangerous warrior in the Tornian Empire. He is the King of Luda, the Emperor's blood brother, but the dynasty will end with his death. He would have no offspring without a woman to mate with him, because he was crippled and declared “unfit.” The Tornian Empire had been dying since a terrible disease caused almost the entire female species to degenerate. Every year fewer and fewer girls were born. Since then, the men of the Tornian Empire began to look for females compatible with them in all known Universes. But the Emperor’s discovery about the presence of compatible women on a slave ship changes everything. He orders Grim to find the homeworld of his Empress in order to obtain more "unprotected" females, knowing full well that Grim will never be allowed to mate with one of them. Lisa Miller is the widowed mother of two little girls, Carly and Mika. Her husband died just a year ago after a long battle with cancer, and she still misses him dearly. Her friends want her to start dating someone again, but Lisa realizes that there will be no man in her heart like her Mark whom she could love and who could love their girls as his own. So Lisa decides to remain alone. But when Lisa is discovered "unprotected" at her husband's grave, she is kidnapped. A woman wakes up on an alien ship, which is heading to an extraterrestrial world. Refusing to accept this, she confronts the huge aliens, demanding to be returned to her children. Seeing a chance to get his own female, Grim is ready to accept and protect her offspring if she agrees to mate with him and only him. Realizing that this is the only way to get her children back, Lisa accepts Grim's condition, and the Tornian Empire changes forever.
