Victoria is a hitman with a long list of dead bodies and an even longer list of issues. The life she knew until now is one "fuck it" decision away from collapsing, as her self-control-the only thing that keeps her demons at bay-shatters, pushing her to the verge of self-destruction. Until she meets Azrael. Ex-human researcher. Current professor. Professional psychopath creator. How do you avoid a killing spree?By letting the psychopath who studies psychopaths do what he knows best: recode her brain. Victoria asks him for help because she's desperate, and he accepts because watching her sanity bleed out in front of him sounds like the most fun he's had in years. Darkest Obsession is the story of what happens when two monsters find the other half of their rotten soul: an obsessive, all-consuming compulsion neither can escape. Darkest Obsession is the first book in the Hell's Flames Duet.
