Obedience by Will Lavender
This thriller is about a college Logic class given a kind of forensic assignment that turns out to be more than just a game. They are told to solve a crime and find a missing person who is supposed to be murdered at the end of the term. The author attended my alma mater, and I could recognize it clearly as the inspiration for the setting, which was kind of cool for me. The book is a mind-fuck, as you’re constantly wondering what is real and what is only a story. I’d call it the undergraduate version of The Magus, which is much longer, more intense, and complex (but maybe more sexist).
