In the soot-stained heart of Birmingham, Hope Montgomery was never just the daughter of a wealthy family; she was a girl forged in the fires of Small Heath alongside the Shelby siblings. Though not a Shelby by blood, she became one through shared childhood mischief, the trauma of the Great War—which claimed her brother James—and a loyalty that even the Peaky Blinders’ razors couldn’t cut. After three years of self-imposed exile in London to escape the ghosts of her brother’s death, Hope returns to find a transformed family. Thomas Shelby, now rising to power and involved with the elegant Grace, finds his icy composure shattered the moment Hope walks back into the Garrison. While Grace represents a new, fragile peace, Hope is Tommy’s "anchor"—the only person sharp-tongued enough to challenge him and the only one who holds the pieces of his pre-war soul. As the brothers (Arthur, John, and Finn) and the matriarch Polly welcome their "sister" home, the delicate balance of the Shelby empire is thrown into chaos. Tommy is forced to confront a devastating truth: despite his ambitions and his new life, he has always loved Hope, and her return proves that she is the only constant he ever truly needed.
