Robber Bride (1999)

[From book's back cover]: Maiden - Warrior - Lover! This was the litany Simon de Burgh chanted whenever he gaze upon Bethia Burnel. Gifted with fighting prowess to rival any of his knights, the maddening woman had laid siege to his vision of how the world should be - and captured his heart in the battle! Simon de Burgh was infuriating - full of raw power and male conviction, even when Bethia had him bound hand and foot, deep in her forest lair. But she would prove to His Arrogance that she could best him yet again - despite her heart's thundering refrain that she had finally met her match!
