I've had this forever but hadn't read it. Perhaps that was a mistake. I can see how the story would've seemed revelatory or daring 10 or 15 years ago.

Essentially it's one man's story of obsession with his girlfriend's brother. He tutors him, takes him on a camping trip, things happen. When they return home our narrator ends up hospitalized, losing tons of weight, and indulging in unhealthy behavior because he can't cope with the rejection of his paramour.

For me it got a bit long and/repetitive but again I'm sure this read differently when it was published.
