The Rose Without a Thorn. (Queen of England Series)

From the pen of legendary historical novelist Jean Plaidy comes an unforgettable true story ofroyalty, passion, and innocence lost. Born into an impoverished branch of the noble Howard family, young Katherine is plucked from her home to live with her grandmother, the Duchess of Norfolk. The innocent girl quickly learns that her grandmother's puritanism is not shared by Katherine's free-spirited cousins, with whom she lives.
Beautiful and impressionable, Katherine becomes involved in two ill-fated love affairs before her sixteenth birthday. Like her cousin Anne Boleyn, she leaves her grandmother's home to become a lady-in-waiting at the court of Henry VIII. The royal palaces are exciting to a young girl from the country, and Katherine's duties there allow her to be near her handsome cousin, Thomas Culpepper, whom she has loved since childhood.
But when Katherine catches the eye of the aging and unhappily married king, she is forced to abandon her plans for a life with Thomas and marry King Henry. Overwhelmed by the change in her fortunes, bewildered and flattered by the adoration of her husband, Katherine is dazzled by the royal life. But her bliss is short-lived as rumors of her wayward past come back to haunt her, and Katherine's destiny takes another, deadly, turn.
