The Girl Who Stopped Swimming by Joshilyn Jackson

Laurel Hawthorne wakes up one night to see a ghost at the foot of her bed. It is the ghost of Molly, a friend of Laurel's 13-year-old daughter, Shelby. Molly has just drowned in the Hawthorne's swimming pool. As Laurel tries to understand how Molly ended up dead, dark family secrets come to the surface. Her perfect life in a gated Florida community is turned upside-down. I listened to an audiobook narrated by the author, which added the dimension of the voices of the Southern setting. The ghost aspect may make this sound creepier than it is; I found it rather frothy, but entertaining.
