London Ruthless Books in Order

London Ruthless pulls readers into a version of London where sleek boardrooms and exclusive clubs sit on top of a much darker criminal world. At its core is the tangled relationship between Samantha Donovan and Gabriel Sullivan, a woman running from abuse and the ruthless man she once called her angel.

It’s a duet about first love, second chances and the ways power can both wound and protect.

In Dark Angel, Samantha is desperate to escape the grip of a violent ex. Gabriel has always been off-limits—too dangerous, too connected, too close to her family—but he’s also the only person who has ever made her feel wholly seen. When he steps in to help her, she finds herself drawn into his world of backroom deals, loyalty tests and quiet brutality.

Fallen Angel picks up after Gabriel makes a choice that shatters that fragile trust. The book leans into heartbreak, resentment and the slow, painful process of deciding whether the love between them can survive betrayal. Samantha isn’t a passive heroine; she fights for her safety and her future, even when that means walking away from the man she loves.

Later, Heart of a Devil expands the London Ruthless world with a new couple, bringing in a heroine who has fled the sunshine and baggage of Los Angeles for a quieter life in the UK. Instead she falls for Sebastian Donovan, her best friend’s father and a man with his own ties to the city’s criminal underbelly. The age gap, best-friend’s-dad dynamic and heavy Daddy Dom energy make this story darker and kinkier while still circling themes of trust and survival.

Across the series, Kincaid balances smoky glamour with real emotional scars. Violence is never far away, but the focus stays on the characters—how trauma shapes them, how family can both cage and protect, and how two people decide whether to risk everything for another shot at happiness.

London Ruthless also connects loosely to the wider Ruthless universe. Readers who move on to the L.A. or New York books will spot familiar surnames and cross-reference cameos, while new readers can treat these novels as a self-contained slice of dark, twisty London romance.
