Have you ever read a book where, when you were finished, you were pretty sure there was some kind of subtext (or some such thing) that went right over your head? I have, and that book is By The Time We Leave Here, We'll Be Friends by J. David Osborne
The book is set in a Soviet-era Siberian gulag. The main characters are all prisoners and guards. There's drug use. There's a throat parasite. There are placentas wearing diapers. There are tattoos. There is violence.
Heck, I'm not really sure how to explain it. I will say that even though I didn't really understand it, I did enjoy it.
