PSA: If you're looking for a light read, do NOT pick up Side Life by Steve Toutonghi. Just because it's thin and has cats on it doesn't mean it won't fill you with oppressive existential dread and make you not able to sleep at night.
Just to clarify: this isn't a recommendation for it as an existential-dread inducer. I didn't even really like it that much tbh -- the characters are all kind of unlikeable, and there are some scenes where I feel like the author wanted to see how uncomfortable he could make the audience.
