The kingmaker's daughter - Philippa Gregory (The Plantagenet and Tudor Novels #4)

"If you are going to be Queen of England, he won’t let you fall," Isabel says shrewdly.

"If you are going to be Queen of England, he will love you and serve you every moment of the day.

You’ve always been his pet… you should be glad that now you are at the centre of his ambition."

Anne Neville and her sister Isabel are daughters of the most powerful magnate in 15th century England, the Earl of Warwick, the Kingmaker, born with royal blood in their veins.
Widowed at fourteen, fatherless, stripped of her inheritance and with her mother locked in sanctuary and Isabel a vengeful enemy, Anne faces the world alone.

But fortune’s wheel is always turning. Plotting her escape from her sister’s house, she finds herself a husband in the handsome young Duke of Gloucester and marries without permission.

Danger follows her, and she finds she has a mortal enemy in the most beautiful queen of England. Anne must protect herself and her precious only son from the treacherous royal court, her deadly royal rival, and even from the driving ambition of her husband, Richard III.
