What book got you out of a slump?

I’m just wrapping up my senior year of Highschool and want to get back into reading now that I have more time on my hands.

I have very eclectic tastes in books so I’m open to whatever you guys really enjoy. For reference, I mostly read fiction and I’m looking for a stand alone that I can breeze through. Genres I currently like are YA, fantasy, dystopia, romance, and memoirs, but I’m open to trying anything. Tell me what books you couldn’t put down.
