If you've read 13 Reasons Why, then you'll get the picture
Basically this girl named Hannah Baker commits suicide(using pills, hence the pills in the picture) and she does it because of certain people who madeher life hell. SO she records her story about those who made it happen on a voice recorder and send the cassete's to them through mail a day before she commited suiced. And that's why there's the casette tapes there.
In my opinoin, it was an extremel good novel, and I couldn't pt it down, I finished it in like 2 days. It's a sad one too, but I highly reccomend it.
So can you see the connection between the picture and the book?
