It is called Whatever Happened to Kevin Kane?. Here is the synopsis, if you are debating reading it (which you should). The synopsis is not very good, but at the time of writing it (read: 9AM) I was very tired and pulled it out of my ass. Cut me some slack.
Remember that one guy at your school who was really smart but then everyone forgot about (well, except for you, if you were friends with him)?
This is his story.
I hope you enjoy this tale of mystery and intrigue.
