Highlander Assassinated by Rebecca Preston

When professional bodyguard Lissa Crossworth escapes to Scotland for a much-needed vacation, the last thing she expects is to find herself in 16th-century Scotland—or to be mistaken for the reincarnation of a Highlander’s lost love…

After stepping through a mysterious doorway in the mist, Lissa meets Niall MacClaran, a skilled negotiator haunted by the death of his wife, who looked exactly like Lissa. While grappling with her startling new reality, Lissa is drawn into a dangerous web of political intrigue involving the MacClaran clan, an English inquest, and a sinister plot to assassinate an ally. Determined to prove her worth, Lissa uses her modern skills to navigate the treacherous waters of diplomacy and defend the people who have welcomed her into their lives.
As sparks fly between her and Niall, Lissa must confront her own doubts about whether his feelings are for her—or the memory of his late wife. Their bond is tested as they uncover a plot to eliminate Lord Weatherby and replace him with a puppet hostile to the Scots. Together, Lissa and Niall must use their wits and strength to uncover the truth, protect their allies, and prevent disaster.
