Butcher & Blackbird

Butcher & Blackbird by Brynne Weaver (2023) is the viral first installment of the Ruinous Love trilogy. It single-handedly popularized the “Dark Romantasy” and “Serial Killer Rom-Com” subgenres on social media, famously described as “Dexter meets When Harry Met Sally.”

The Plot: A Deadly Competition
The story follows two rival serial killers who only target other “bad” people:

• Sloane (“The Blackbird”): A meticulous, artistic killer who specializes in intricate, symbolic disposals.
• Rowan (“The Butcher”): A charismatic, somewhat chaotic chef who kills with brutal efficiency.

After a chance encounter in a remote location (involving a very small space and a very dead body), they develop an unlikely bond. They establish an annual competition: once a year, they meet in a different city to hunt the same target—a notorious predator who has escaped justice. Whoever kills the target first wins. Over several years of these “kill-dates,” their professional rivalry turns into a deep, albeit dysfunctional, romantic obsession.

Key Appeal Notes

• The “Slow Burn”: Despite the graphic nature of their hobbies, the emotional relationship between Sloane and Rowan is a multi-year slow burn that focuses on mutual understanding and “being seen” for who they truly are.
• Dual POV: The narrative alternates between Sloane and Rowan, allowing readers to see Rowan’s absolute (and often hilarious) “golden retriever” devotion to Sloane, contrasted with his lethal skills.
• Dark Humor: The book leans heavily into “gallows humor,” finding comedy in the logistics of body disposal and the absurdity of their situation.
• Graphic Content: Unlike “cozy” mysteries, this book is extremely explicit regarding both violence and romance. It is intended for a mature audience and comes with a long list of trigger warnings.
