When Edouard de Lanceau, son of Moydenshire's great Lord Geoffrey de Lanceau, finds an unconscious wounded woman lying in a river, he's shocked to recognize Lady Juliana de Greyne, to whom he was once almost betrothed. The previous year, his bet with a friend to win her kiss went awry, and the commitment to her never proceeded. When Juliana's sister deceived him into betrothing her instead, Edouard became honor-bound to wed her; yet he still desires Juliana. Taking her in his arms, he vows to discover who would want her dead—and why.

While riding to an important meeting on behalf of his ill father, Edouard must face Lord Geoffrey's enemies, who have returned to Moydenshire to destroy him. Taken prisoner and chained in a tower, Edouard must fight not only for his life but for Juliana's as well. When Juliana wakes, she has no memory of who she is or what happened to her. She only knows she's captive in a chamber alongside a man in chains who insists he knows her.

For reasons unknown, her feelings for this stranger run strong. Were they once lovers, or is he a cold-blooded killer? Determined to regain her memories and know the truth, Lady Juliana discovers that nothing can vanquish love or the power of a knight's persuasion.
