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.
