Carlos is Gonna get it (Exposition)

The main characters in the book are, Trina, Sara, Thea, Frankie, Donte, and the really weird kid Carlos. The group of friends get along pretty well and they are pretty popular. They are getting very tired of this kid in their class named Carlos, Carlos can cause a lot of trouble but his actions cause others to get in trouble instead of him. This has been going on for over a year now. They're now in 7th grade and they want to get Carlos back for all the trouble he's been causing them. So far this book has been written in kind of an angry tone but also a bit confused tone because it's from Trina's point of view and she is bothered by Carlos but she also doesn't really care and sometimes sees him as a regular kid.
