"I bought your remaining days, Seraphina. Every breath you have left belongs to me." Seraphina Sterling has exactly ninety days to live. Diagnosed with an incurable heart defect, she refuses to die in a sterile hospital bed. Instead, she walks straight into the den of the city’s most ruthless, hidden predator Valerius Vance. She knows his dark secret. She knows his grandfather’s will demands he marry a pure human woman to keep his multi-billion-dollar empire. The contract they sign in blood is simple: She will play the part of his doting, completely pampered billionaire wife. In exchange, he will give her a lifetime of breathless luxury, shielding her fragile human body from the world. When the ninety days are up and she passes away, he remains a grieving widower in permanent control of his crown. No strings attached. But living under the same roof with a dominant, fiercely protective vampire blurs the lines. His cold compliance turns into a consuming, territorial passion. Valerius ruins her for any other man, teaching her human heart to beat for him alone. Then, the clock hits zero. As Seraphina dies in his arms, Valerius refuses to let her go. To rip her back from the edge of death, he executes a forbidden royal ritual, binding her soul to his immortal blood. But the supernatural law demands a brutal sacrifice: to buy her immortality, Valerius must surrender every single memory of her. When Seraphina wakes up healed, vibrant, and immortal she turns to her protector, only to freeze. The warmth in his eyes is gone. Standing before her is the ice-cold billionaire who views her as a total stranger, an intruder who somehow tricked him into a marriage contract. Even as his vampire instincts violently demand her touch, his mind registers her as the enemy. Trapped in a mansion with a ruthless king who doesn't remember her name, Seraphina must make a choice: flee the dark underworld, or force a monster to fall in love with her all over again.
