Grace Evans is a Watcher. A Watcher's job is to protect the future and the past, making sure history happens as it should. Her next mission, given to her by The Council, is her most demanding yet. Grace must travel back to the Scottish Highlands of 1746 to stop Highlander Euan Cameron from rejoining the Jacobite Army at all costs and dying in battle at Culloden. It is a task easier said than done, as Euan is dedicated to his chief and his clan and would rather give up his life in battle than walk away like a coward. Can Grace save him without breaking all the rules and altering their lives and history forever?
