This was a quieter style of suspense with great themes that explored the relationship between mothers and daughters and all the complexities that are present in that dynamic. I love the authors style, her writing is so strong and she has an evocative way of telling a story that always speaks to me. The social media angle always fascinates me and since Charlie and Eva shared a popular joint account there was a lot to explore here. NB does a great job at looking at the dark side of social media all while creating a suspenseful story of a missing person. If you like character driven mysteries with depth this was good.
