Title: The girl on the train
Author: Paula Hawkins
Year: 2015 
Synopsis : EVERY DAY THE SAME
Rachel takes the same commuter train every morning and night. Every day she rattles down the track, flashes past a stretch of cozy suburban homes, and stops at the signal that allows her to daily watch the same couple breakfasting on their deck. She's even started to feel like she knows them. Jess and Jason, she calls them. Their life--as she sees it--is perfect. Not unlike the life she recently lost.

UNTIL TODAY
And then she sees something shocking. It's only a minute until the train moves on, but it's enough. Now everything's changed. Unable to keep it to herself, Rachel goes to the police. But is she really as unreliable as they say? Soon she is deeply entangled not only in the investigation but in the lives of everyone involved. Has she done more harm than good?





Thoughts 
Rachel is a very relatable character, her life isn't the best but that doesn't stop me from admitting she has no self-respect she keeps calling her married ex-husband who cheated on her and refuses to move on. When losing her job she looks for no options and instead takes a train everyday into London and observes a couple. So far rachel is no role-model but I can understand why she is the way she is. 
I like the concept and the way it makes the story mysterious I don't care so much about the characters. 
There's Tom and Anna her ex-husband and wife which are parents to a baby girl. Then there's also Cathy:Rachel's roommate and her boyfriend , I forgot his name (not relevant) and Scott and Megan.
Scott and Megan are the couple that lives across Rachels old house and the same she has been watching every morning since she lost her job. 
The rest of the book is about finding out what happened to Megan when she suddenly disappears.
