Mine’s The Unabridged Journals of Sylvia Plath. Thick books never stopped me from reading nonstop before, but there are entries in the book that just has me stopping and taking time to mull things over.
Also, sharing this excerpt: “Not to be sentimental, as I sound, but why the hell are we conditioned into the smooth strawberry-and-cream Mother-Goose-world, Alice-in-Wonderland fable, only to be broken on the wheel as we grow older and become aware of ourselves as individuals with a dull responsibility in life?”
Currently The Left hand of Darkness, by Ursula L. le Guin. I’ve been reading it on and off since September and I’m still only on page 100.
Thought it was going to be a quick read but I’m finding the prose quite difficult to understand (English is my second language)
Longer than that was A Song of Ice and Fire, which was on my reading list for almost two years before I decided that I was never going to finish it, and finally shelved it.
