Books that make you want to sleep and chillll. I want to feel like a couch potato dog who spends their time dozing by the fire

My solution for everything is to do more exercise. It's a very bad solution. I get ill more often than other people and always take over a week to recover from minor colds. So I thought I'd ask you guys for help, because nothing can change my mindset like a book can!

Looking for fiction not self help. Any kind of lazy cozy playful fiction
