Brynne Weaver Books

Brynne Weaver had written fantasy and paranormal romance for years without much fanfare, and then in 2023 she self-published Butcher & Blackbird and became one of the fastest-rising names in dark romance almost overnight. The book, a romantic comedy about two serial killers who hunt other serial killers and fall for each other over an annual murder game, was the kind of word-of-mouth hit that publishers chase for decades. TikTok made it enormous, Zando's Slowburn imprint picked it up for traditional publication, and the special editions started selling out before they shipped. Within a year she had gone from midlist obscurity to seeing her covers everywhere.

The pitch sounds like it should not work. Sloane Sutherland is a quiet, surgically precise killer who targets predators; Rowan Kane is a Boston restaurateur with the same hobby and considerably more charm. They meet over a mutual victim, start an annual competition, and spend years as long-distance best friends who are obviously in love and comically slow to admit it. The tone is the trick: Weaver plays the gore for shock and the romance completely straight. Under the viscera it is a friends-to-lovers slow burn with grand gestures and genuine tenderness, which is why readers who normally avoid dark romance ended up loving it, and why hardened dark romance readers sometimes find it too cute for their tastes.

The Ruinous Love trilogy continued with Leather & Lark (2024), pairing Rowan's hitman brother Lachlan with Sloane's musician best friend Lark in a marriage-of-convenience setup, and closed with Scythe & Sparrow (2025), which follows the third Kane brother, Fionn, a doctor who patches up a vengeance-minded circus performer named Rose. Reader consensus ranks Butcher & Blackbird first, Scythe & Sparrow a strong finish, and Leather & Lark as the divisive middle child. In 2025 Weaver launched a new series, Seasons of Carnage, starting with Tourist Season and continuing with Harvest Season in June 2026, keeping the same formula: body count, banter, happily ever after.

Spice is a full 4 on our 0-5 scale, occasionally brushing 5. The scenes are frequent, explicit, and inventive, and they arrive alongside dismemberment played for laughs. Content warnings are not optional here: graphic violence, torture, references to past abuse and trafficking (the villains tend to richly deserve what they get), and dark humor about all of it. Weaver includes warnings in the books themselves, which is the correct call, and you should actually read them.

Now the honest framing: Weaver is not romantasy. There is no magic, no fae court, no prophecy. She is in this database because the Venn diagram of her readers and romantasy readers is nearly a circle, and because she delivers something romantasy readers constantly ask for: a morally black love interest whose devotion is absolute. Rowan Kane is functionally a shadow daddy without the shadows. If you have read every vampire and rewritten every villain into a boyfriend, Weaver is the logical palate cleanser, the same emotional beats with contemporary knives instead of enchanted ones. Her actual romantasy roots do show in her earlier self-published fantasy work, but nobody starts there, and honestly neither should you.

Start with Butcher & Blackbird, obviously. If the first chapter's gore makes you laugh rather than close the book, you are the target audience; the trilogy reads best in order since couples recur and the overarching villain plot pays off in book three. Read the content warnings first, take the humor as permission not to take any of it seriously, and keep Scythe & Sparrow on deck for the finale. Then, when you want the same wicked-banter energy back in a fantasy setting, come home to the vampires. They will still be here waiting.
