The Perfect Sister by Stephanie DeCarolis
The Perfect Sister is a mystery/thriller set in the Hamptons. It starts with Alex who is desperate to find her older sister. She had a falling out with her sister, Maddie, after their mom died. Alex travels to the Hamptons after she can't get a hold of her sister to find out what is going on. Alex connects with Lily, the daughter of a wealthy family, and finds out that her sister had been staying with them. As Alex digs deeper the mystery slowly starts to unravel, however there is so much more to the story than she ever imagined. This was a good book with a solid plot and twist at the end. What I really enjoyed was that the novel was told in multiple viewpoints. It was great to see into the minds of all of the main characters to see what their motivations might be. A great summer novel filled with thrilling moments and mystery!
