A man who says he was once Crown Prince Dorian Valmont wakes in a six-year-old's body and is presented to the Valmonts as their long-lost fourth son. His arrival sparks rejection: sisters Vivienne and Imogen sneer and call him a filthy bumpkin. The grandmother alone offers warmth, telling him to call her Grandma. Adopted son Aldric fears losing his place, but his parents say, "You'll always be our favorite." Officially acknowledged yet treated as an outsider, Dorian is left exposed in a household split by favor and scorn, and a clear rivalry is born.
