What’s a sci-fi book I should read as someone who is just getting back into reading books again?

Long story short, when I was young I was an aggressive reader. When kids would get caught for using their phones during the night with having to wake up for school the next morning (that happened too), I was the kid who used the phone light under the bedsheet to use as light for reading until the late A.Ms. Kinda like Harry Potter reading under the bedsheet in the books and movies.

But I loved reading and I thought I would always love reading. The library was my favorite place to be in the city, regardless of time. I churned out books by the week. Adn the genre I was reading was purely and only fantasy.

But then school at some point started to force us to read certain books that I just had no interest in. And having to force myself to read through books in genres that I had no interest in and also the books not being gripping enough, or the fact that I had to sit down and write my interpretation of what I had read and it being faulted for being wrong just rubbed me the wrong way.

So I stopped reading fully. It wasn't fun anymore.

But now in my mid-20s, I really want to get back into reading again. The local book/comic/board game/everything store had an outlet store where they're selling the books and stuff that they can't sell for full price anymore. So they're selling it for 85% off which means the books sre dirt cheap.

And even though growing up, the most I've read is fantasy, sci-fi is my homeground and my favorite genre. But I don't know too many sci-fi books apart from some very specific ones, like The Expanse, Foundation by Isaac Asimov (which I bought the first book for), Project Hail Mary and The Martian.

I've now started reading the Stormlight Archive by Brandon Sanderson and I've bought some of The Wheel of Time books. The only really sci-fi book I've got is Foundation as I don't know which ones I should be looking for.

So could you people recommend me some sci-fi books that I should be on the lookout for when I go back to the Outlet store next?

Would be very greatful, thank you!
