When Martian Air Science Engineer Cass Hedley takes a dare to use her new Artificial Intelligence system for a night of erotic release, there's only one man she can imagine spending time with—the legendary comic book hero Star Knight Errant. She imagines strong hands, hard abs, and bubble baths, but her black market AI has another idea—an illegal fight club that will only end in her sexy companion's death…or hers. When Evander Mór transports to an unknown desert planet, his mission changes. Instead of brokering a peace deal, he'll figure out what backwater he's landed on and enjoy a well-earned weekend off with a gorgeous scientist. But when things get hotter than a supernova between them, he discovers he only has eighteen hours to stop an AI bent on murder, convince Cass he's more than fiction, and find a way to cross the gulf between galaxies to bring her home.
