The Conqueror — Georgette Heyer

A fictionalized biography, fast-moving and minutely-wrought chronicle about William, Duke of Normandy who became King of England in 1066.

The day she gave birth to William, the beautiful Herleva dreamt that a tree sprang from her womb--a giant among trees, whose mighty branches overshadowed all of Normandy and England. No sooner her half-noble bastard of the Duke of Normandy had grown to manhood than he forced the Norman lords to call him their Duke, and fought the King of France to regain his Duchy.

Only one woman could match William the Bastard's lovely little Princess Matilda of Flanders. Rejected his proposal of marriage, Duke dares to take a whip to her in her own father's palace, before making her his bride. In his strange and brutal way, he would conquer her too...

Then, thwarted by the Saxon warrior Harold of a promise of the throne of England, he gathered his vassals once more to challenge him. William the Conqueror sails to Hastings to claim the Saxon King's crown and sceptre for his own.
