a mix between Heathers and Catcher in the Rye

apparently this book came out before Heartstopper and was slightly adjusted and republished after it. It follows Tori Spring, Charlie’s older sister, set during Vol 4 of Heartstopper. There are quite a few nick and charlie moments which are cute 

This books heavily deals with mental health issues. The main character is an unreliable narrator due to her mental health issues and is extremely depressed and su*cidal. Charlie also has a relapse in this book.

The plot itself is absolutely bonkers. It had a mystery revolving around an entity that is organizing dangerous pranks at school but it also follows Tori as she slowly builds and breaks relationships and navigates her mental health.
