Haunting Highland House, by Kathryn Hills

A time travel romance set in the present and the mid-1880s centered on an old New England house. What really stood out for me about this novel was that when Samantha (“Sam”) travels back in time, her brief visits jump around in time, so you have this fascinating situation where Robert (the ghostly owner) experiences Sam out of sequence - each time they meet, she’s at one stage of their relationship and he’s at another. I really, really liked this non-linear development of their relationship.
