At eighteen, Maple Quinn Tempest desperately needs income to support her younger sister. When her friend suggests an unconventional job—bodyguarding a vampire—Maple's immediate reaction is skepticism. Vampires are notoriously powerful; why would one require human protection? Her friend insists this vampire is different, that he faces threats beyond typical danger. Despite her reservations and the absurdity of the situation, Maple's financial desperation wins out. She agrees, though she never imagined the position would begin quite so abruptly. Before she can properly prepare, the vampire arrives at their café meeting spot. A striking figure with dark hair emerges from a limousine, accompanied by suited bodyguards, radiating the unmistakable aura of wealth and aristocracy. Maple realizes too late that she's about to step into a world far removed from her ordinary student life—one where danger takes on an entirely new meaning, and protecting a vampire prince may require far more than martial arts skills. As their unlikely arrangement begins, questions linger: What threats does this vampire truly face? Why does he need her protection specifically? And in a world of darkness and danger, can Maple survive the complications that arise when duty becomes something far more dangerous than she ever anticipated?
