Sure. 'The Lake House' is also very popular. It combines a modern - day mystery with a historical story. The way she blends the two time periods is really fascinating. Also, 'The Clockmaker's Daughter' is a great example of her historical fiction. It has a complex plot with multiple characters and their stories intertwined with historical events.
I would recommend 'The Secret Keeper'. It's a gripping tale that involves a mother's past and the secrets she has kept. Kate Morton is really good at creating these complex family relationships within a historical context. And 'The Distant Hours' is another of her notable works, set in an old castle and full of historical charm and mystery.
