Written by Dr Sung-Yoon Lee, a scholar and specialist on North Korea who has advised the US government, The Sister is a jaw-dropping account of the spectacular rise of Kim Yo Jong, de-facto deputy to her brother, Supreme Leader Kim Jong Un, and the most powerful woman in North Korea. In 2022, in a particularly fiery speech, Kim Yo Jong threatened to nuke South Korea, reminding the world of the dangers posed by her state.

But how did the youngest daughter of Dear Leader Kim Jong Il, his ‘sweet princess’, become the ruthless chief propagandist, internal administrator and foreign policymaker for her brother’s totalitarian regime?The Sister uncovers the truth about Kim Yo Jong, her close bond with Kim Jong Un and the lessons in manipulation they learned from their father. Lee also examines the iron grip the Kim dynasty has on their country, the grotesque deaths of family members deemed disloyal, and the signs that Kim Yo Jong has been positioned as her brother’s successor should he die while his own children are young. Readable and insightful, this book is an invaluable portrait of a woman who might yet hold the survival of her despotic dynasty in her hands.
