   Summary

   When a loving married couple from Earth mysteriously awaken in the grim darkness of the Warhammer 40,000 universe, they find themselves trapped in opposing forms — she as a Tyranid Termagant, and he as a stoic Ultramarine. Their humanity and memories of each other begin to fade, swallowed by the instincts of their new bodies: her mind pulled toward the all-consuming Hive Mind, and his toward duty, discipline, and devotion to the Imperium. Racing against time and the corruption of their souls, the two must find each other across a war-torn galaxy — and rediscover their love — before they are lost forever to the nightmare they’ve become.
