The Heiress was a wild ride. I am not someone who reads synopsizes often, so I honestly had no idea what I was getting into with this one. I have read almost all of Rachel Hawkins's books. This ones started out with a cute little romance with some weird underlying secret. 
It quickly delved into a dark history and a crazy family. There were quite a few twists and turns that kept me intrigued. I really enjoy the plot that started when a child was taken from a family picnic and then returned to her family, and the generations of trauma that spurred from that moment. 
I think my favorite aspect was the location, I loved the southern Appalachian mountains and the huge house. That set the coolest vibes in the story.
