The London Ruthless series by Sadie Kincaid moves her dark mafia romance world across the Atlantic to London. The series began with Dark Angel in 2021, followed by Fallen Angel the same year, and Heart of a Devil in 2025.
Kincaid is known for writing intense, steamy romances set in the criminal underworld, and the London Ruthless books bring that formula to a British setting. The “angel” and “devil” imagery in the titles hints at the push and pull between danger and desire that drives the stories.
The series exists in the same universe as Kincaid’s popular New York Ruthless and Manhattan Ruthless series. While the London books feature their own characters and storylines, readers who are already invested in the Ruthless world will recognize connections between the series. Each book delivers dark romance with possessive heroes and high-stakes tension.
