William Marshal's skill with a sword and loyalty to his word have earned him the favor of kings, the lands of a magnate, and the hand of Isabelle de Clare, one of England's wealthiest heiresses. But he is thrust back into the chaos of court when King Richard dies.

The vindictive new king clashes with William, claims the Marshal lands for the Crown—and takes two of William's sons hostage. The price of his loyalty to the Crown suddenly seems too high and the very heart of William and Isabelle's family is at stake. Fiercely intelligent and fearing for the man and marriage that light her life, Isabelle plunges with her husband down a rebellious path that will lead William to more power than he ever expected.
