It's interesting that the counselors are so mean. There are a lot of things about the 1980s that I have forgotten existed, and this may be one of them. Certainly, their methods would find them out of a job very quickly in today's world!
love Berk's The Dark Days of Hamburger Halpin (2010), Guy Langan, Crime Scene Investigator (2012) and Strike Three, You're Dead (2013) mainly because they are actually murder mysteries. This is more along the lines of Hahn's ghost mysteries, such as Took or The Girl in the Locked Room. Mitchell seems to write more for YA audiences. This was a great summer camp romp, but my students would probably wish it actually had more murder in it. (Which sounds so, so wrong!)
