The Glass Bead Game by Herman Hesse, it probably one of the easiest Nobel Literature winners to read.
I'm a sucker for slow burns in cinematography and books, but you can't just have no pace or structure and then say "yeah, these kids have no patience".
My completely uneducated opinion of the glass bead game was that Hesse was describing what could be a very interesting concept in a very poor manner, always high-level, and abstract enough that at times I thought he didn't flesh it out in his mind either and couldn't convey it properly.
