May 1665. With winter passed, Mercia Blakewood is at last headed back to England from America, hoping to leave behind the shadow cast by death and heartache. She expects a welcome from the king considering her earlier mission on his behalf, but the reception she receives after her long voyage home could hardly be called warm.
