Catherine de Medici

Catherine was born into one of Italy's most powerful families, and in 1533, at the age of 14, was sent to France to Marry King Henri. They had three sons who ended up wearing the crown, and after the Kings sudden death, it was rumored she used any means necessary to ensure they kept it. If you love renaissance France and/or royalty, here's some novels I found on this infamous queen you should check out:

The truth is, not one of us is innocent. We all have sins to confess. So reveals Catherine de Medici, the last legitimate descendant of her family’s illustrious line. Expelled from her native Florence, Catherine is betrothed to Henri, son of François I of France. In an unfamiliar realm, Catherine strives to create a role for herself through her patronage of the famous clairvoyant Nostradamus and her own innate gift as a seer. But in her fortieth year, Catherine is widowed, left alone with six young children in a kingdom torn apart by the ambitions of a treacherous nobility. Relying on her tenacity, wit, and uncanny gift for compromise, Catherine seizes power, intent on securing the throne for her sons, unaware that if she is to save France, she may have to sacrifice her ideals, her reputation, and the secret of her embattled heart.

Confidante of Nostradamus, scheming mother-in-law to Mary, Queen of Scots, and architect of the bloody St. Bartholomew's Day Massacre, Catherine de Medici is one of the most maligned monarchs in history. In her latest historical fiction, Jeanne Kalogridis tells Catherine's story—that of a tender young girl, destined to be a pawn in Machiavellian games.
Born into one of Florence's most powerful families, Catherine was soon left a fabulously rich heiress by the early deaths of her parents. Violent conflict rent the city state and she found herself imprisoned and threatened by her family's enemies before finally being released and married off to the handsome Prince Henry of France.
Overshadowed by her husband's mistress, the gorgeous, conniving Diane de Poitiers, and unable to bear children, Catherine resorted to the dark arts of sorcery to win Henry's love and enhance her fertility—for which she would pay a price. Against the lavish and decadent backdrop of the French court, and Catherine's blood-soaked visions of the future, Kalogridis reveals the great love and desire Catherine bore for her husband, Henry, and her stark determination to keep her sons on the throne.

Young Catherine de' Medici is the sole heiress to the entire fortune of the wealthy Medici family. But her life is far from luxurious. After a childhood spent locked away behind the walls of a convent, she joins the household of the pope, where at last she can be united with her true love. But, all too soon, that love is replaced with an engagement to a boy who is cold and aloof. It soon becomes clear that Catherine will need all the cunning she can muster to command the respect she deserves as one of France's most powerful queens.

Fourteen-year-old Catherine de’ Medici arrives in Marseilles to marry Henry, Duke of Orleans, second son of the King of France. The brokenhearted Catherine has left her true love in Italy, forced into trading her future happiness for marriage into the French royal family.
Amid the glittering fêtes and banquets of the most immoral court in sixteenth-century Europe, the reluctant bride becomes a passionate but unwanted wife. Humiliated and unloved, Catherine spies on Henry and his lover, the infamous Diane de Poitiers. Tortured by what she sees, Catherine becomes consumed by a ruthless ambition destined to make her the most despised woman in France: the dream that one day the French crown will be worn by a Medici heir...

When Catherine de' Medici was forced to marry Henry of Orleans, her's was not the only heart broken. Jeanne of Navarre once dreamed of marrying this same prince, but like Catherine, she must bend to the will of King Francis's political needs. And so both Catherine and Jeanne's lives are set on unwanted paths, destined to cross in affairs of state, love and faith, driving them to become deadly political rivals. Years later, Jeanne is happily married to the dashing but politically inept Antoine de Bourbon, whilst the widowed Catherine continues to be loved by few and feared by many - including her children. But she is now the powerful mother of kings, who will do anything to see her beloved second son, Henry, rule France. As civil war ravages the country and Jeanne fights for the Huguenot cause, Catherine advances along her unholy road, making enemies at every turn...

The aging Catherine de’ Medici and her sickly son King Charles are hoping to end the violence between the feuding Catholics and Huguenots. When Catherine arranges the marriage of her beautiful Catholic daughter Margot to Huguenot king Henry of Navarre, France’s subjects hope there will finally be peace. But shortly after the wedding, when many of the most prominent Huguenots are still celebrating in Paris, King Charles gives an order that could only have come from his mother: rid France of its “pestilential Huguenots forever.” In this bloody conclusion to the Catherine de’ Medici trilogy, Jean Plaidy shows the demise of kings and skillfully exposes Catherine’s lifetime of depraved scheming.
