The
Golden Notebook by Doris Lessing sprang to mind immediately on reading this thread, although I think it's the only book of that kind I've read. It was lauded by all sorts of eminent critics, but the narrator's self-obsessiveness nearly sent me into a decline, and although determined to find out what had prompted such fulsome praise I had trouble finishing the 500 or so pages. I never did understand.
I've just been to amazon to check the title - it was a long time ago that I read it - and the first review expresses exactly how I felt about it at the time. This book may be the reason I tend to avoid all highly-hyped novels these days.
Life of Pi fell from my hand half way through, and I haven't felt inclined to pick it up since.
