The Girl on The Train: A Novel by Paula Hawkins | Honest Review and Summary

Rachel Watson used to have a settled life, but since her marriage ended she has drifted through her days in a haze of drinking. Having lost her job, she still rides the commuter train into London and back each day, watching the same scenery slide past the window. Each morning the train slows near the street where she once lived, and there she notices a couple who seem to have a flawless existence in a lovely house. Rachel begins to imagine their lives, building stories about their hopes and private troubles to distract herself from her own. Then something happens that pulls her into the lives she has been observing, and she finds herself caught up in events far beyond her control.
