New Reign Mafia Duet Books in Order

If you like mafia romance where attraction and danger arrive at the same time, the New Reign Mafia Duet is one of the clearest windows into Shain Rose's darker side. Heart of a Monster and Love of a Queen follow Rome Armanelli and Katalina across one continuous romance, so this series works best when read straight through.

Nothing here is clean or easy.

Rome is the feared enforcer for a powerful Italian crime family, and Katalina is one of the few people who sees the man under that reputation. That is the main pull of the series. She is drawn to the exact man she should fear, while he keeps trying to shove her away even after their lives become tightly linked. The chemistry is intense from the start, but so is the mistrust.

The setting matters because these books run on power, loyalty, and the feeling that private emotions never stay private for long. Family obligations, blood ties, and old bargains shape every decision. Even when the story slows down for longing or intimacy, the mob world is still pressing in from all sides, reminding both characters that love does not happen in a vacuum.

Because this is a duet, the emotional arc has room to breathe. Heart of a Monster builds the connection, the danger, and the reasons Rome and Katalina cannot simply walk away. Love of a Queen picks up with the fallout, pushing them into harder questions about betrayal, allegiance, and whether they can still choose each other when the people around them want something else.

Expect obsession, possessiveness, and a lot of push and pull.

Even with the mafia backdrop, the real engine is emotional. Rose writes this pair as two people who keep colliding because the stakes around them are too high for half measures. If you want an angsty, darker entry point into her interconnected world, this is a strong place to start.
