"The girl on the train" is a mystery, thriller book by Paula Hawkins, It's a beautiful book to read and it will make you curious to finish the book as you progressed reading it.
The Story typically revolves around three woman named Rachel, Megan and Anna.
Rachel is protagonist in this book who travels everyday on train from London to Witney while observing a couple in a house near to track. One day, when she saw different man in the house kissing the girl how the life of Rachel changed completely, this is what depicted in this story.
I personally enjoyed every line of this book, the helplessness of Rachel, the charm and mystery of Megan, and protective mother Anna.
The book is definitely a must read if you enjoy thriller and mystery kind of books.
