Getting back into reading and would love some fun lighthearted stories.

As the title suggests, I've recently decided to pick up reading/listening to audiobooks as a new hobby. Unfortunately, I'm not very well versed in the literature world as I was back in highschool.

I'm currently reading "There are rivers in the sky" by Elif Shafak. because it's themes of time, memory, and culture. Not incredibly far in yet, but I don't think it's exactly what I'm looking for right now. I still plan on reading it, but would like to begin a backlog for future reference.

Any book is welcome as a suggestion, but Id especially love recommendations of sci-fi, fantasy, psychology, or interesting history!

Thank you in advance!
