A.D. 1203: The Lady Elizabeau Treveighan is the illegitimate daughter of Geoffrey, Duke of Brittany. Elizabeau was sent to foster at a very young age, her identity known only to herself and the earl who fostered her. When her half-brother Prince Arthur is murdered and rumors begin to fly that the opposition to King John intends to marry her to a Teutonic prince and supplant her and her new husband as the rulers of England, she suddenly becomes a very hot, and very dangerous, commodity.

Sir Rhys du Bois is charged with keeping Elizabeau safe until her arranged marriage can occur, but the task turns into one of monumental proportions. It's one harrowing flight after another as Rhys tries to keep Elizabeau from harm's way. Somewhere in the process, they fall madly in love with each other and the knight finds himself battling duty and love in order to stay on task. Torn, but with a tremendous sense of duty, he cannot escape the feelings that are swamping him, and Elizabeau does not make it easy for him. Her love for him supersedes her loyalty to her country, and to a family name that has only meant heartache for her.

When Elizabeau is finally captured by the king's men and slated for execution under the charge of treason, Rhys will risk everything to save her from the executioner's sword. However, Rhys is betrayed by another knight and soon, he too is slated for the executioner's axe. As Rhys and Elizabeau face death together, allies come together for a covert operation that will save their lives. It's a race against time before King John's men can execute the last legitimate heiress to the throne and her protector turned lover.
