Katharine Parr, the sixth wife / Alison Weir.

Having sent his much-beloved but deceitful young wife Katheryn Howard to her beheading, King Henry fixes his lonely eyes on a more mature woman, thirty-year-old, twice-widowed Katharine Parr. She, however, is in love with Sir Thomas Seymour, brother to the late Queen Jane. Aware of his rival, Henry sends him abroad, leaving Katharine no choice but to become Henry's sixth queen in 1543. The king is no longer in any condition to father a child, but Katharine is content to mother his three children, Mary, Elizabeth, and the longed-for male heir, Edward. Four years into the marriage, Henry dies, leaving England's throne to nine-year-old Edward, a puppet in the hands of ruthlessly ambitious royal courtiers, and Katharine's life takes a more complicated turn. Thrilled at this renewed opportunity to wed her first love, Katharine doesn't realize that Sir Thomas now sees her as a mere stepping stone to the throne, his eye actually set on bedding and wedding fourteen-year-old Elizabeth. The princess is innocently flattered by his attentions, allowing him into her bedroom, to the shock of her household. The result is a tangled tale of love and a struggle for power, bringing to a close the dramatic and violent reign of Henry VIII.
