Paula Hawkins
La ragazza del treno

A book on the borderline.
The chaos of alcoholism, boredom, teenage recklessness, and selfishness. All mixed with male violence and marital domineering.
A story entirely told in the first person and from a female perspective. Three women alternating with big mood swings and fear of the present.
A fast-paced, very original read. I enjoyed reading the fears and insecurities of the protagonist, Rachel.
A woman who loses her husband, job, home, and friends because of the drinking habit.
Despite this, every morning she takes the train as if she were going to work.
Every day, from the train, she sees a happy couple making out on the balcony in the morning. She invents names for them and fantasizes about their life. Until the day she sees a different man on the balcony passionately kissing the woman.
She has no time for reflection because the news shows the photo of this woman, Megan, who has disappeared without a trace.
The journey of the protagonist is fantastic between moments of clarity and post-binge chaos.
Then psychological violence circulating in the romantic and investigative plot.
That's it, I won't say more.
Excellent. I recommend the reading.
