Mistress of the Sun - Sandra Gulland

The author of the internationally acclaimed Josephine Bonaparte trilogy returns with another irresistible historical novel, this one based on the life of Louise de la Valliere, who, against all odds, became one of the most mysterious consorts of France's Louis XIV, the charismatic Sun King.
Set against the magnificent decadence of the seventeenth-century French court, Mistress of the Sun begins when an eccentric young Louise falls in love with a wild white stallion and uses ancient magic to tame him. This one desperate action of her youth shadows her throughout her life, changing it in ways she could never imagine.
Unmarriageable, and too poor to join a convent, Louise enters the court of the Sun King, where the king is captivated by her. As their love unfolds, Louise bears Louis four children, is made a duchess, and reigns unrivaled as his official mistress until dangerous intrigue threatens her position at court and in Louis's heart.
A riveting love story with a captivating mystery at its heart, Mistress of the Sun illuminates both the power of true and perfect love and the rash actions we take to capture and tame it.
