Scythe & Sparrow

Fionn Kane is the youngest of the three Kane brothers, a small-town doctor who keeps his quiet streak of justice-killings hidden behind the medical practice and the family loyalty that anchors his life. Rose is a circus knife-thrower with a closed-down past, a list of names she has not finished crossing off, and zero interest in being saved by anyone. A bike accident lands Rose in Fionn's clinic, the two of them recognize the same predator-instinct in each other inside the first conversation, and Weaver closes the Ruinous Love trilogy with the friends-with-benefits register the first two books built toward. The book hit number one on the New York Times bestseller list the week of release and held the dark-romance charts through spring 2025.
