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?”
Sapiens by Yuval Noah Harari. I started it back in July 2019 for my work’s book club, finished and went to the pub event for the parts 1 and 2, realized I couldn’t make the second meeting for parts 3 and 4 and stopped reading. At the start of 2021 I made a pact to finish it…which resulted in me reading one additional chapter and putting it down again. It is still sitting on my “currently reading” list on goodreads.
