During a sudden and violent outbreak of a werewolf virus, college student Emma becomes trapped in a subway station. Just as she is about to be killed, she is rescued by Caleb, the mysterious “Alpha King.”
Emma is taken to a secluded estate, where she learns a shocking secret: her blood contains rare natural antibodies, and only a child conceived by her and Caleb can make it possible to develop the ultimate serum—one capable of eradicating the virus and saving humanity.
To rescue a world that has descended into hell, Emma has no choice but to accept a contract to bear Caleb’s child. As they begin living together at the estate, danger, desire, and forbidden attraction draw them closer with each passing day.
