This is a thrilling story told in an unconventional way. It mirrors actual society in which we get multiple perspectives from lots of individuals in the community, both related and unrelated to the event. The three main “Promise Boys” are all students with different friend groups, personalities and motives for the murder. But who is the killer? 

I think this is a great YA which manages to mirror the real world, use technology in a way that isn’t dating to the book, and provide some misdirects that work!
