1684, Scottish Highlands

Englishwoman Evelyn Worthington is resolved to build a school for ladies in her brother's newly purchased Scottish castle. But when she arrives, not only does she find the castle scorched by fire, but a brawny Highlander bars her entry.

Clan chief Grey Campbell would rather die than see his family home, Finlarig Castle, fall into English hands, so Grey must win the battle of wills with the beautiful Sassenach who flashes a bill of sale before him.

When the war between Evelyn and Grey escalates, passions flare. But outsiders have their own plans for Finlarig. After secrets are revealed, and muskets are lit, the fates of the Campbell Clan, the school, and a possible future for Grey and Evelyn are in as much jeopardy as their lives.
