Nocturne by Karina Halle

Seven meets L.A. Confidential with a vampire twist, in this true crime and film noir-inspired standalone dark romance from New York Times Bestselling author Karina Halle.

In 1940s Los Angeles, the murder of Lena Reid’s closest friend, Elizabeth Short, known as the Black Dahlia, shocks the city and leaves whispers of a serial killer stalking the shadows. Drawn to danger and desperate for answers, Lena crosses paths with Victor Callahan, an ex-boxer turned private detective with a tormented soul and haunted past.
Their connection is fiery, obsessive and depraved, but as the investigation deepens, Lena discovers a darker threat lurking beneath Callahan’s carefully controlled exterior.
The blackouts he can’t explain.
The nights he can’t remember.
The blood on his hands.
With each passing night, something primal awakens within him—a heritage concealed since birth. Callahan is hunting a killer while unaware that vampire blood runs in his veins, transforming him into something both powerful and dangerous.

As they uncover the terrifying truth behind Elizabeth’s murder, Lena and Callahan are thrust into a twisted game of love, lust, and violence. In a city where monsters wear human faces, they have no choice but to confront the predators stalking them—and the ones lurking within.
