He was branded a traitor. And he may be humankind's salvation…
Captain Nikolas EstherVorn is a traitor. Or so it was decreed after Niko disobeyed protocol while trying to save Earth from other-dimensional creatures. Stuck in a prison cell, the last thing he needs is to be in close proximity to sexy-as-sin Dr. Sarah CallenJoseph. Not with him damn near ready to break out just to get to her.
Niko's desire isn't quite his own…and Sarah can prove it. He—along with the other soldiers on the disastrous mission—were drugged with some kind of toxin. Niko has no clue how the drug got into his body or why, but Sarah suspects there's a link between the toxin and the fertility crisis of Shipborn humans.
To investigate is forbidden. But as lust becomes something deeper, binding them together in a way neither expected, Niko and Sarah must battle time—and their superiors—to uncover the secret that could save humanity…or destroy it.
Tropes: This apocalypse set romance novel features a redemption arc, coworkers in space, the military, an alpha male, and a marriage of convenience. There's also a matchmaker, but I don't want to spoil anything.
