Owned by My Ex’s Godfather follows 22-year-old Lila Hart, who accidentally spends the night with Damian DeLuca—only to discover that the dangerous Mafia boss is her boyfriend Caden’s father. After Caden betrays her with her best friend, Damian openly pursues Lila, turning one forbidden mistake into an intense relationship.
Their romance is threatened by a dark secret surrounding Lila’s father, Michael Hart. Lila is led to believe Michael was a traitor killed by Damian, but the truth reveals that he was actually Damian’s undercover informant who sacrificed his life during a dangerous mission. As enemies manipulate the past and Caden becomes increasingly obsessed with revenge, Lila and Damian are forced to fight for their relationship and their unborn child.
After the final betrayals are exposed, Caden learns that he was adopted and loses everything. Damian saves Lila once again and brings her back to the place where they first met. This time, instead of another dangerous mistake, he offers her a ring—and Lila chooses him for good.
