One Bite Rule

She came for the cheap rent. She stayed because Viktor Wright already knew her name, because the city needed saving, and because six-foot-four ancient vampire kings who say twelve words a day and leave books outside your door are apparently her specific problem. Isabela Torrez is a broke folklore PhD with nowhere else to go and entirely too many questions. The gothic mansion has one rule. She breaks it on night one and keeps breaking it until the whole underground is on fire.
Viktor Wright is an original vampire, a reluctant king, and two hundred years of controlled restraint aimed directly at her. The slow burn is real. The heat when it breaks is explicit. The blood war is personal. One Bite Rule. She bit first. He remembered it forever.
