Birmingham, 1962, and the coldest winter in memory grips the streets around the Cadbury works. Seventeen-year-old Greta finds warmth only among her fellow chocolate girls, her home life a misery she longs to escape. A hasty marriage to Trevor promises freedom but delivers heartbreak, leaving her alone and expecting a child with nowhere to turn. It is the unexpected kindness of old family friends Edie and Anatoli that offers her a way back, though tragedy is never far behind. A properly moving Birmingham saga, warm at its core and unafraid of hard truths.
