In this intimate portrait of Princess Sibylla of Sweden, renowned royal historian Roger Lundgren reveals the remarkable life of one of Europe's most misunderstood royal figures. Born a German princess in 1908, Sibylla married into the Swedish royal family and faced the challenge of raising five children—including the current King Carl XVI Gustaf—alone after her husband's tragic death in 1947.

Drawing on exclusive interviews and previously unpublished correspondence, Lundgren reveals how this strong-willed princess navigated the complexities of being a German royal in post-war Sweden while preparing her young son for his future role as king. A poignant story of duty, resilience and motherhood in the face of personal tragedy and public scrutiny.
