Found this tweet from the previous time I read Les Miserables, back in 2013. I took several breaks to read other books, including the environmental dystopia The Windup Girl by Paolo Bacigalupi:
I’ve been reading The Windup Girl. It’s very good, but I’m ready to go back to Les Miserables for something more cheerful.
