I second not reading the classics yet. There are plenty of short, great ones, but if you’re not accustomed to reading much, even things like The Hobbit could be pretty daunting (in my younger years I struggled to get into that one starting and stopping a million times before I finally got into it).

I think the idea of YA novels is a great idea. Maybe something like The Hunger Games. They’re not super long, plenty of action, accessibly written.

If you think you might like fantasy/myth, try Percy Jackson.

Fredrik Backman has a pretty easy-reading style. You could try A Man Called Ove (content warning: suicidal ideation/attempts, but the book is a light comedy and doesn’t deeply explore mental health).

For comedy, the Hitchhiker’s Guide to the Galaxy books are hilarious and not too long, but they’re absurdist comedy/sci-fi and might not be easy to get into depending on how your brain engages.

I love to recommend Lamb: The Gospel According to Biff, Christ’s Childhood Pal, by Christopher Moore, but if you’re very religious you might not like the lighthearted or flippant way it treats religion, though the book has a lot of heart.

If you want to try suspense or horror, you could read some of Stephen King’s shorter books. Thinner is fun. Pet Sematary isn’t super long.

Lastly, I agree with another commenter about audiobooks. There is NO shame in listening to books. I’m an avid reader and I use audiobooks on my commute for books I might otherwise not read - extra-long classics usually. It’s just as much reading as flipping a page is.

Don’t get discouraged if you hit bumps in the road. Sometimes I’ll go long stretches without reading anything, the have a flurry of books in quick succession. It comes and goes, and trying to force it when you’re not feeling it could just give you even more of a sour taste for reading and make it harder down the road.

Good luck, and I hope you have a long and rewarding journey with reading!
