She is brilliant. She is stubborn. And she is about to walk into the most dangerous case of her life. When the most powerful mob boss in New Orleans is found dead in his office without a single mark on his body, Viv is the first investigator on the scene. What she discovers chills her to the bone. The killer is not human. It is not vampire, shifter, or witch. It is something ancient. Something that was supposed to be extinct. Something that kills by consuming the soul itself. A shadow wraith has come to the French Quarter. And someone is controlling it. Enter Cade Thorne. Rugged. Secretive. Dangerously attractive. A shifter bounty hunter who grew up on the roughest streets of New Orleans and clawed his way out through sheer will and wolf instinct. He is tracking the same killer for reasons he refuses to share, carrying a personal vendetta that goes deeper than he will admit and a secret about his own changing abilities that terrifies him. Viv doesn't want a partner. Cade doesn't do teamwork. But when a second victim falls and the body count threatens to climb, these two stubborn, fiercely independent investigators have no choice but to join forces. The problem? Working together means getting close. And getting close means confronting an attraction so intense it borders on combustion. Every argument sparks. Every glance lingers. Every accidental touch sends electricity through them both. They agreed to keep it professional. They agreed to deal with their feelings after the case. Some agreements were made to be broken. As the investigation deepens, Viv finds herself caught in a web of secrets that stretches far beyond one murder. A mysterious organization called The Obsidian Order offers her a partnership that promises resources and reach but demands a trust she is not sure they have earned. Her own family is hiding something. Something connected to the killer. Something that could change everything Viv believes about who she is and where she comes from. And Cade, the man she is falling for despite every rational instinct telling her not to, is keeping the biggest secret of all. The clock is ticking. The shadow wraith is growing stronger, feeding on the supernatural energy of New Orleans itself. The killer's plan is centuries in the making, rooted in a betrayal so old and so deep that it threatens to tear apart the very foundations of supernatural society. Viv has fourteen days to find the summoner, sever the bond, and destroy the wraith before the French Quarter is consumed. To do it, she will need to embrace every part of herself. The vampire she has spent her life suppressing. The witch she has always relied on. And the woman who is learning, for the first time, that letting someone in might be the most powerful magic of all. She will need to trust people who might not deserve it. She will need to forgive a family that lied to protect her. She will need to stand beside a man whose own transformation mirrors hers in ways neither of them expected. And she will need to face a villain who is not a monster but a mirror. A man who was wronged, who was forgotten, who was erased from history by the very people Viv's family descends from. A man whose rage is justified even if his methods are unforgivable.
