Much like 
 Gone Girl 
 , I couldn't sympathize with a single character because they were all awful, but unlike 
 Gone Girl 
 I felt this story told the harrowing tale more efficiently and with more depth. 
 Rachel is a messy drunk who happens to see something while riding the train everyday that makes her think twice when a woman's whose house she passes everyday ends up missing. The only problem is who will believe a drunk? 
 What I enjoyed about the story was the different perspectives of the story and how for most of the time we are seeing everything from the blurry view of Rachel. But we switch up to a POV of the missing woman, and Rachel's Ex's new wife. Three women telling the story about lives that are far from perfect and terrible secrets in a relatively sleepy neighborhood. 
 Despite my lack of love for any of the characters, including those you'd normally feel sympathy for, I enjoyed the movement of the story, the revelations and the mysteries which kept me interested throughout the entire story.
