The book is about 5 people getting detention, and only 4 making it out alive. You read the whole detention scene in the book with 2 or 3 povs. The book is not scary at all. It gives several clues and little notes, it's totally not boring and isn't hard to get into. The plot twist and how everthing got reveald was pretty genius. Had my jaw on the floor. I bet you wont see the plot twist coming either :) Btw it has a romance sub plot and it's so cute! <3 Defienetly recommend, can't wait to read the 3rd book coming out in a few days.
