A mysterious distress call draws the crew of the Hermes to what appears to be an empty, drifting ship. Empty that is, except for the blood and gore-spattered corridors and one lone survivor locked in a holding cell. Drawn to the handsome, traumatized man, the crew's comm officer, Isaac Ozawa, makes Turk his personal responsibility, offering him the kindness and warmth he needs after the horror he experienced. Turk longs for Isaac, a desperate, hopeless ache he knows he'll always carry with him. But Turk harbors dangerous secrets, his brain a military experiment gone wrong. When an amoral, power-hungry admiral kidnaps Isaac and uses him to convince Turk to become the cataclysmic weapon he's hungered for, it will take Turk's strength, the ingenuity of the Hermes crew, the help of the enigmatic Drak'tar, and Isaac's own stubborn will to save them.
