n 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?
