Titans: Moretti Mafia Books in Order

Titans: Moretti Mafia is one of Sierra Cartwright's darkest branches, taking the possessive energy of her billionaire romances and dropping it into a family world ruled by vengeance, loyalty, and forced marriage. These books are not soft-edged power fantasies. They are built around men who have been raised to treat family duty as law and love as a vulnerability they can barely afford.

The series opens with Vengeful Vows, where a Moretti heir targets Bella as retribution for a loss that still burns. Savage Vows centers on Matteo, a mafia prince who chooses duty over love until runaway bride Alessia makes that position impossible to hold. Merciless Vows goes darker still with Dante Moretti, who kidnaps enemy's daughter Valentina after his father is murdered and tries to turn revenge into leverage. Of course, emotion has other ideas.

These books are about possession in the most dangerous sense.

Brides are taken, bargains are enforced, and rival families turn romance into strategy. The women are often placed inside systems they did not build and cannot control, which is why their resistance matters so much. Cartwright gets a lot of tension from that push and pull. The men may believe they own the board, but the women are usually the people who change the game.

Expect obsession, family politics, and moral lines that are blurry at best. The Moretti heroes are not polished corporate alphas with a secret soft side waiting politely to emerge. They are enforcers, heirs, and power brokers shaped by violence and legacy. When they love, it is rarely gentle at first.

That darker mood is the main reason to read this branch. If the original Titans books give you secret society glamour, Moretti Mafia gives you danger, retaliation, and marriages that feel like acts of war until they start turning into something more personal. The stories still promise emotional payoff, but they take a rougher road to get there.

Pick this series if you want Sierra Cartwright at her most ruthless. It is moody, possessive, and much more openly driven by family vendettas than her other connected worlds.
