Brynne Weaver

Brynne Weaver is an American author who broke out on BookTok with The Ruinous Love Trilogy, a dark romantic comedy series about an extended family of serial killers who only fall for partners able to handle their murderous hobby. Comprising Butcher & Blackbird, Leather & Lark, and Scythe & Sparrow, the trilogy pairs a different family member or in-law with a love interest in each book, playing the premise for both horror-adjacent tension and genuinely comic banter, leaning on chaotic-good murder logistics, running family jokes, and a doggy daycare the family operates as a cover day job rather than pure grimdark bleakness. That balance of shock-premise and comedy is a large part of why the series went viral as a palate cleanser between heavier dark romance reads. Each book in the trilogy is a self-contained romance for a different couple, with earlier pairs recurring as supporting characters and family in later installments. New readers should start with Butcher & Blackbird, the series opener, to meet the family from the beginning. There is no film or television adaptation of the trilogy to date. The Ruinous Love Trilogy concluded as a complete three-book series with Scythe & Sparrow in 2025, and Weaver has continued writing within the dark romance genre since.
