Jenny Ocean's life is already on shaky ground when a violent attack sparks a chain of events that leaves her with a terrible secret that she can share with no one, and which clouds her every waking moment with guilt and fear for years to come. Trying to make amends, Jenny works hard and becomes a professional counselor dedicated to helping others unravel their problems. For a time, it seems her life is finally on track, but her past catches up with her in the form of Rio Winston. At first an enigmatic client, Rio turns out to be a narcissistic serial killer who leverages her past to draw her into a web of complicity in his delusional and homicidal mission. Jenny becomes trapped in a confusing, dark journey mixing horror and fascination, balancing her coerced alliance with Rio with her affair with police detective Sam Longford-only to find that the distance separating a killer from the law isn't as great as she once thought. Featuring a trio of characters bound together by desire, obsession, grandiosity, and remorseless need, Harm Reduction journeys into the depravity of serial murder, the pain of ambivalence, moral compromise in the face of survival, and the tenuous hope of finding a way out.
