About L.A. Ruthless
Sadie Kincaid’s L.A. Ruthless series is a dark mafia romance sequence centered on the Montoya crime family, power, forced loyalty, and love stories that unfold inside a world where control and danger are part of everyday life. The series includes Fierce King, Fierce Queen, Fierce Betrayal, and Fierce Obsession, with the first two books focusing on Alejandro Montoya and Alana Carmichael, while the later books shift toward Lucia Montoya and Jackson Decker. Together, the books form one of Kincaid’s key Ruthless-world series, sitting alongside her New York, Chicago, London, and Manhattan mafia-romance branches.
The opening book, Fierce King, establishes the central power structure through Alejandro Montoya, the feared “King of L.A.,” and Alana Carmichael, a woman pulled into marriage with him under circumstances shaped by family pressure and survival. Their relationship begins from imbalance, fear, and resistance rather than softness, which sets the tone for the series as a whole. Alana is not simply entering a glamorous criminal world; she is being forced to understand its rules, its violence, and the way loyalty can become both protection and captivity.
Fierce Queen continues Alejandro and Alana’s story rather than moving immediately to a new couple. That continuation matters because their romance is not designed as a quick enemies-to-lovers arc that resolves all tension in one book. The second installment deepens the consequences of their marriage, testing whether attraction and devotion can survive betrayal, family conflict, and the pressure of ruling beside a man whose life is built on power. Alana’s role also changes. She is no longer only the woman forced into Alejandro’s world; she has to decide what kind of strength, authority, and identity she will claim within it.
The series then shifts with Fierce Betrayal, which focuses on Lucia Montoya and Jackson Decker. Lucia is Alejandro’s adopted daughter, and Jackson is tied to the Montoya world as an older, dangerous, deeply embedded figure. Their story changes the emotional angle of the series by moving from forced marriage and mafia-rule dynamics into a forbidden, age-gap romance shaped by loyalty, restraint, and the danger of wanting someone who should be off limits. Kincaid uses that tension to explore desire inside a family power structure where every relationship carries consequences.
Fierce Obsession continues Lucia and Jackson’s arc, giving their relationship the same two-book treatment that Alejandro and Alana receive. This structure is important to the series’ rhythm. L.A. Ruthless is not a set of four unrelated mafia romances; it is built as two connected couple arcs inside the Montoya family world. Each pair is given room for escalation, fallout, and emotional reckoning, while the broader atmosphere of criminal power and family loyalty remains constant.
The appeal of L.A. Ruthless lies in its heightened emotional stakes. Kincaid writes a version of mafia romance where love is rarely calm and safety is never guaranteed. Her characters are possessive, wounded, proud, and often morally complicated, but the relationships are driven by devotion as much as danger. The Montoya family setting gives the series its identity: a Los Angeles underworld of wealth, fear, loyalty, and reputation, where romance can become another form of power.
L.A. Ruthless is best understood as dark romance rather than crime fiction. The criminal world supplies the pressure, but the emotional focus is on obsession, trust, betrayal, and the difficult transformation from possession into chosen loyalty. For readers following Sadie Kincaid’s wider Ruthless universe, this series is one of the central family branches, especially because it gives the Montoyas a full emotional arc across two generations of romance.
