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?”
Suicide by Edouard Levé - Aside from its heavy subject, it is also written in 2nd person which I find difficult to get a flow going with. That and there aren’t a lot of natural breaks.
The Dragon Never Sleeps by Glen Cook - I am a big fan of Glen Cook’s Black Company and Garrett P.I. series. This one is pretty different from his other works and so I have been slowly making my way through.
