In the shadowed world of Vale Biotech, twenty-three-year-old medical student Lena Moreau takes a desperate internship as the personal assistant to enigmatic billionaire Sébastien Vale. Cold, brilliant, and dangerously magnetic, Bastien is a man who avoids touch, only meets after dark, and seems determined to drive her away. Yet the more he pushes, the deeper Lena is drawn into his darkness. Bastien is a 400-year-old vampire who swore never to crave human blood again, until Lena walked into his life. She is the spitting image of the only woman he ever loved… and the only one whose blood could destroy his hard-won control. Torn between his growing obsession and the fear of becoming the monster he despises, Bastien fights their forbidden attraction with every icy breath. But an ancient vampire cult led by his ruthless sire has other plans. When they come for Lena, Bastien will unleash centuries of rage to protect her, risking everything, including her very soul.
