Sadie unexpectedly became bound to a mystical force that granted her repeated life, but each resurrection consumed a terrifying amount of soul energy. She deeply loved Nicholas and was willing to protect him from danger over and over, sacrificing her lives as if they were nothing. However, Nicholas grew indifferent and numb to her deaths, treating her sacrifice as a mere convenience. He even had the cruelty to allow her to take a fatal blow meant for his secret first love. Disheartened, Sadie agreed—but Nicholas remained unaware that this was her absolute last chance at life. Only after Sadie’s presence vanished from the world forever did Nicholas learn the truth. Now, he is overwhelmed by a remorse that can't be calculated. A moving supernatural romance of high-society regret.
