But before he leaves, he intends to kill Lord Foxworth Morgan for his deceit and cruelty. Poor Lady Zoe Morgan is a weak and frail thing.

Kidnapped by Keegan, Zoe must live long enough to warn her brother Fox who might possibly be in Scotland. Saddled with the constantly complaining Lady Zoe, Keegan questions his judgement in kidnapping her in the first place. But she is the bait that will lead him to her brother. As their adventures progress, Keegan and Zoe change their opinions of each other even as she continually tries to escape. As enemies become allies, their mutual attraction blossoms into passionate love.
