9780749021146 Allison and Busby
February 1665. With winter passing, Mercia Blakewood is at last headed back to England from America, hoping to leave behind the shadow that death and heartache have cast. She expects a welcome from the King considering her earlier, mostly successful, mission at his behalf, but the reception is not exactly warm.
Mercia faces more manipulation and must accept a clandestine and uncomfortable role at the heart of the royal court posing as a mistress to find a spy and traitor.
