When brilliant bioengineer Damian Ross develops a revolutionary strain of programmable moss?capable of being 3D-printed into nutritious food and thriving on carbon dioxide and human waste?he believes he's solved two of humanity's greatest crises: sustainable space travel and global hunger. His invention is more than food. It's a closed-loop life-support ecosystem.

Enter Lucas Taylor?astronaut, visionary, and billionaire founder of Red Star Rising, a private aerospace company racing to establish humanity's first permanent research center on Mars. Lucas sees in Damian's breakthrough the missing piece that could make long-duration missions not only viable, but economically transformative.

When Lucas personally recruits Damian for the inaugural Mars mission, professional admiration quickly gives way to undeniable chemistry. Training in isolation chambers, long strategy sessions, and the high-pressure world of private space exploration draw them closer. Both men are accustomed to control?Damian in the lab, Lucas in the boardroom and cockpit?but in each other's presence, that control begins to slip.

As their relationship deepens, so does the danger.

Corporate rivals, threatened governments, and shadowy investors circle Red Star Rising. Someone wants Damian's research?and is willing to sabotage the mission to get it. Data breaches, mysterious accidents, and whispered betrayals force Damian and Lucas to confront a terrifying possibility: the greatest threat to Mars may not be the planet itself.

With the launch window approaching and trust in short supply, the two men must decide what they're willing to risk?for science, for the future of humanity, and for each other.

In a story where passion and ambition burn as fiercely as rocket fuel, love may be the most dangerous mission of all.
