I was so excited to read Glass Bead Game. I waited till the end, having read most of Hesse's other major works before tackling his magnum opus. I was so disappointed in it, and I too put it down. Part of me wonders if something was lost in translation with that work.
I read a French translation of it a decade ago and remember it as a fairly interesting book. It has an intriguing premise which it uses cleverly to explore a large range of subjects, is fairly well written and is an interesting commentary on what constitutes a bildungsroman.
It is not particularly plot driven however so I'm a bit confused by the idea of it going somewhere.
I suppose technically I have abandoned it too, but I will never admit to it. I fully intend to pick it up again and finish it so it sits on the shelf and stares at me instead.
