what moral lesson have you learned?

This is asking for your opinion. I think that Appearances Are Deceiving is one of the dominant themes within the novel also applies to the novel itself. Many reviewers have noted that at first glance, the story looks like it may be The Breakfast Club for the social media age. What starts out as an eclectic group of high students sharing detention, however, very quickly erupts into a murder mystery. The narrative of that murder mystery being investigated in turns results in characters who initially appear to conform to stereotypes eventually revealing layers of complexity. Notably, Simon’s death appears to be a murder, although it is in fact a suicide.
