The Other Gwyn Girl by Nicola Cornick

1671 – London
The Civil War is over and Charles II, the ‘Merry Monarch’, is revelling in the throne of his murdered father and all the privileges and power that comes with it. Sharing the spoils is his favourite companion, the celebrated beauty, actress Nell Gwyn. Beloved of the English people, Nell has come a long way from selling oranges and a childhood in a brothel, but as her fortunes have turned, her sister Rose has taken a different path. Marriage to a feckless highwayman has left Rose in the grim Marshalsea prison and now she needs her sister’s mercy to help get her out. But Nell needs Rose too. A plot to steal the Crown Jewels has gone tragically wrong, and Nell’s future with her protector King is at risk. If Rose can’t solve the riddle of the jewels both Gwyn sisters will head straight to the Tower.
