Between this and Gone Girl, I really like how women writers are pretty much reclaiming the "girl who disappeared" genre. 
 Here, I love how the story is absolutely centered on women. I love how they're allowed to be (extremely) flawed and somewhat unlikeable, all the while very complex. I loved discovering their stories, masterfully led by the author. The pace can be slow at times, yet very compelling; it's hard to put the book down. 
 I'm a bit afraid of the upcoming movie, there's so many ways in which it could miss the point - and from the trailer and the cast list, there's already been some changes I'm not sure about. I guess we'll have to see.
