Bent on delivering a treasonous letter to save her cause, Jacobite rebel Isabeau Macpherson is captured mid-flight by the enemy. Her captors are not the English, but more despised still - fellow Scots fighting against Bonnie Prince Charlie.
The only sentence for a Jacobite traitor is death, but their enigmatic leader takes her prisoner instead. Despite her obvious hatred for him and all that he represents, Alistair Campbell is bewitched by his fearless and beautiful charge. When Isabeau escapes and is captured by the English and tortured, he risks everything to free her and make her his own.
Torn between loyalty to her cause and love for a man who is her sworn enemy; Isabeau is forced to take sides in a battle that threatens to destroy them both.
