Doc. Redcars, #4

Raised in hell. Remade in blood. Levi is a mercy that he won't survive. Doc has lived his whole life in the shadows, using sharp skills and colder instincts to keep his sister and her kids safe. He fixes problems no one talks about, navigates dangerous circles without leaving a trace, and has learned that survival means staying hidden, staying in control, and never letting anyone close enough to see the cracks.
Detective Levi Rosen is the exception he never planned for. Levi should walk away the moment he realizes Doc is tied to a world of underground violence, organ traffickers, and buried bodies. Instead, he finds himself drawn to the man behind the mask-the quiet precision, the impossible loyalty, and fear buried so deep it barely shows. Together, they're forced to navigate a violent network, shifting loyalties, and a past that's been hunting Doc since he was a boy.
And Levi has to decide how far he's willing to go for a man who doesn't believe he deserves to be saved. Doc is a dark, emotional MM romantic suspense about trauma, obsession, forced proximity, morally grey choices, found family, and choosing someone even when the world keeps trying to take them away. This is Book 4 in the Redcars series and should be read in order.
