The invasion of an alien race known as the Friem has left humanity cowering in fear and hiding in underground bunkers as the invaders ravage the planet. The surviving humans are hunted to be used as slave labor, and those who fight are killed. For what remains of the resistance, resources are slim and time is running out. Like all of her half sisters, Sage was genetically enhanced for the fight against the Friem. Bred to be a warrior, she’s tough, bitchy, and mean, and there isn’t a damn person on the planet who can best her in a fight. A law unto herself, she gives little thought to what people think of her because if something needs doing, she knows she’s the one they call. The only person she really needs is herself, until Gideon enters the picture. As the only pilot around who can provide the training she needs, she’ll do whatever it takes to work with him. When playing nice to get what she wants subtly changes to something more, will Sage let him in? Or will this tough-as-nails warrior fight those feelings to the bitter end?
