The Three Crowns: The Story of William and Mary (A Novel of the Stuarts)

When an empire is at stake, one woman stands between the past and the future
 
In post-Restoration England, King Charles II has fathered numerous bastards, but not a single legitimate heir. Because of this, his brother, James, Duke of York, is heir-presumptive to the thrones of England, Scotland, and Ireland—the three crowns of Britain. But James’s devout Catholicism, and desire to return Britain to the rule of Rome, does not sit well with his subjects and his time as king is sure to be short.
Raised under the Protestant guardianship of her uncle King Charles, James’s daughter Mary finds herself at fifteen facing a marriage to the Dutch and Protestant William of Orange, long prophesied to be destined for the throne. But can she follow her calling to rule Britain without losing the love of her father?

Captivating in its historical detail, lush and sweeping in its scope, and unforgettable in its dramatic depiction of relationships between monarchs and families, The Three Crowns is the singular story of the only joint sovereigns in British history.
