Oooh that's a hard one because it's so different for all readers! I always bounce between books I can easily consume and practically have memorized, so for me those would be Memoirs of a Geisha, Jurassic Park, or Interview with the Vampire. And depending on how viciously I need to come out of a deeper book, I'll reread an entire series from my younger days like Animorphs or hunger games 😂

My husband calls it the "rebound read" every time he catches me reading Memoirs of a Geisha or Jurassic Park. He's not wrong lol

Whenever I encounter this, I read one of my rebound books. They snap me out of the blues until I find a new world I'm willing to invest in.

I'm immediately researching dad-jokes for moms

It really depends; I will read anything that comes my way from whatever source (bookstore, library, a friend's house etc.) And if I greatly enjoyed it, I'll buy it. With series I only purchase the 1st book if it's good and borrow the rest.
