Perfect for you if...

  • You love dark romance where the hero is genuinely dangerous and the heroine isn't just a love interest but a strategic player with her own agenda.
  • You crave that specific tension of enemies-to-lovers where the emotional stakes match the physical peril, and betrayal feels earned rather than convenient.
  • You're drawn to possessive heroes and obsessive dynamics when they're grounded in real danger: she could trigger a war by loving him.

Maybe not for you if...

  • You need your heroes morally grey but ultimately good. Dillan is a mob boss first, and the book doesn't apologise for what he is.
  • You're uncomfortable with explicit sexual content or very spicy scenes. This leans heavily into both.
  • You prefer romance where the couple's secrets resolve neatly. Hidden identities here carry genuine consequences and lasting damage.

About this book

A woman takes a job at an Irish mob club with the goal of destroying the O'Rourkes, but her plan unravels when she meets Dillan O'Rourke, the cold and controlled leader of the organization. What begins as an undercover revenge mission becomes complicated by her growing feelings for him. When her true identity and intentions are revealed, the consequences threaten to ignite conflict within his world. Dillan becomes obsessed with protecting her, making her the one thing he will do anything to keep. Mob Boss is the first book in the O'Rourke Brotherhood series. It features an enemies-to-lovers dynamic, hidden identity danger, forced proximity, betrayal, and a possessive antihero whose desire and protection are equally dangerous. The story contains explicit intimate content and explores themes of revenge, obsession, and redemption within a criminal underworld.
