Author bio

Sadie Kincaid is a British romance author who thrives in the spaces where love and danger blur together. Based in the UK with her husband, sons and a permanently unimpressed dog, she writes the kind of stories she likes to read herself: hot, emotional and a little bit ruthless.

Before publishing a single novel, she spent years studying people and systems rather than fictional mob bosses. She holds two BA (Hons) degrees in community and criminal justice plus a diploma in probation studies, and that training shows up in the way she writes power, punishment and consequence.

She started writing seriously in 2016, in the aftermath of losing her middle son. What began as a way to keep her mind busy during a season of grief slowly turned into a new career. Draft by draft, she discovered she could pour both love and anger onto the page and shape them into stories.

At first, those stories took the form of crime novels. Under another name she built a bestselling gangland series, learning how to pace tension and build a criminal underworld that felt real. Eventually she asked herself what would happen if she threaded hard-edged crime fiction together with the kind of intense romance she’d always devoured as a reader.

The answer was Dark Angel, the first book in her London-set Ruthless world. That duet, followed by the L.A., New York, Chicago and Manhattan Ruthless series, introduced readers to wounded heroines, terrifyingly competent crime bosses and found families who close ranks when things get bloody. In books like Fierce King and Ryan Rule, back alleys, penthouse offices and family dining tables are all battlegrounds.

Kincaid didn’t stop at contemporary mafia. With the Broken Bloodlines trilogy, beginning with Forged in Blood, she shifted into paranormal romance, blending magic, prophecy and vampire politics with the same level of heat and emotional fallout. Her later fantastical projects, including A Curse of Blood and the forthcoming King of War, lean into romantasy while keeping the focus firmly on relationships and sacrifice.

Across all of her work you’ll find a few constants: heroines who refuse to stay quiet, men who would burn down empires for the people they love, and a willingness to let characters be messy and morally gray. She’s comfortable writing why-choose relationships, age gaps, best friend’s dad crushes, billionaire office politics or small, brutal choices that haunt a character for years.

Her background in community and criminal justice gives her an eye for how systems trap people, and she often uses that to put her characters in impossible binds. The tension in her books doesn’t only come from guns and threats, but from loyalty, trauma, and the question of what someone is willing to do—and live with—when everything is on the line.

Day to day, Kincaid treats writing like a job but talks about it like a privilege. She shares work-in-progress snippets with a busy online reader community, signs stacks of special-edition hardbacks, and still carves out time to read widely in romance herself. When she’s not plotting new ways to torture fictional couples, she’s usually with her family, walking the dog, or drinking coffee and pretending it counts as research.
