The Princeling (The Morland Dynasty #3)

1558 - Elizabeth I and Mary, Queen of Scots

Protestantism is sweeping the land and threatens the position of the Catholic Morlands, so they must seek new spheres of influence. John, the heir, rides north to the untamed Borderlands to wed the daughter of Black Will Percy, Northumberland cattle lord. But he finds he must first prove himself, and win her heart through blood and battle. John's gentle sister Lettice is given in marriage to the ruthless Scottish baron, Lord Robert Hamilton, and in the treacherous court of Mary, Queen of Scots, she learns the fierce lessons of survival.
