Billionaire Jerry Donlan has been 26 years old for over 80 years now when he meets Sarah who is a spry 3,000 years old herself. She's also a cold blooded killer, exceptionally strong, and drop-dead gorgeous. They need each other. Jerry needs her to protect him from alien lizards, hell bent on his death, and Sarah needs him to fall in love with her. It's a complicated relationship. Sarah's not into love or emotions. And Jerry? He's not into getting shot at all the time. Together, sort of, they work to unlock the secrets to saving the future of Sarah's people all the while battling deception from their own. They travel to space and back and in the end it's not about science or power or any material trappings. It's all about purpose.
