The Highlander's Stronghold (Searching for a Highlander Book 1)

Ann Borodell is a graduate student who needs a dig site to complete her degree, and the only one open to her is on a remote island in Scotland's Western Isles. Her training lies in colonial America, so the island's sixteenth-century past and the fortress of the Morrison clan that dominates it are unfamiliar ground. Her world tilts when she finds an old blade wedged in the stones of a tower house. Holding it, she is yanked backward through time and wakes in the grip of a wary Highland laird who suspects she is a spy sent by his rivals. Ann is convinced that returning the dagger to its owner, John Morrison, will carry her home. The laird agrees, but he has no plans to let her go, and his stronghold begins to feel harder to leave with every day.
