When the aliens arrived on Earth, it turned out that Plato was right: You really can find your other half - your soulmate.
Pietr may be the most annoying, smug, sarcastic humanoid Matt has ever met. He's also Matt's bonded mate. Plato was right. Everybody really does have a better half, and against everyone's better judgment, it seems Pietr belongs with Matt.
But the hostility between humans and Himika is increasing, and Matt is forced to face some unwelcome truths about his own nature in order to ensure not only his own survival, but that of his fellow human beings as well.
