This book narrates the story of Sophie and Luka, whose relationship appears to be doomed right from the start. When they were children, their fathers arranged their engagement. Despite the significant age difference, Sophie developed feelings for Luka during her school years. However, Luka chose to move to London, aiming to forge his own path and distance himself from his father's criminal activities. Although it's challenging to pinpoint the exact reasons, circumstances spiral out of control, ultimately leading to the separation of Sophie and Luka. "Sicilian's Shock Proposal" illustrates how a lack of communication can profoundly impact a relationship, causing severe consequences.

This story revolves around two individuals who shared a deep love during their childhood, which persists throughout their adult lives. However, Luka carries secrets from the past that he believes Sophie will never be able to forgive him for. On the other hand, Sophie firmly believes that the man who once referred to her as a peasant would never desire to be with her again.
