Suggest me (college student) a book/series to read for fun

I (21) read a lot when I was younger (elementary/middle school). In high school, I mainly read the required books for English, but still read recreationally. Now I'm in college and have barely taken any humanities classes, meaning that I don't have much required reading other than textbooks. I've picked up a few books but am having trouble finding something that really pulls me in. I've started rereading books/series from when I was younger, but I really want to find some new books. I am generally interested in a variety of genres (fiction/fantasy, realistic fiction, bildungsroman, science fiction, romance, etc.). I haven't really read any mysteries besides ones for younger kids (like A to Z Mysteries and Cam Jansen), but I'm definitely willing to try mystery novels.

Here are some books/series that I have really enjoyed:

• Neapolitan Quartet (My Brilliant Friend, The Story of a New Name, Those Who Leave and Those Who Stay, The Story of the Lost Child): I read the first book in high school and loved it so much that I read the other three soon after. This is my favorite series that I have read (I can't really distinguish between the books because it's one continuous story.)
• Harry Potter: I reread the whole series in high school (after initially reading them when I was 7/8) and got really into it; this is one of the series that I've reread a lot since.
• Percy Jackson: I read these in high school having never read them as a kid, but I enjoyed them. I would love to find series that are similar but written more for adults.
• A Wrinkle in Time and its sequels: It's been quite some time since I read the series, but I remember particularly enjoying the science fiction elements of it. It made me interested in learning more about physics, and that's what I'm now studying in college.
• The Curious Incident of the Dog in the Night-Time: I remember enjoying the slight mystery aspect of this book, and it's one of the few books where I remember finding the ending satisfying.
• Out of My Mind: I enjoyed reading from the perspective of the main character.
• The Giver: I started reading the first sequel but did not get far. I just find myself coming back to this book a lot.

I'll add more if I can think of any that really captivated me. I recently discovered the The Infernal Devices trilogy by Cassandra Clare. Are they well-written and interesting for readers who aren't teens? I found some other series that I thought sounded interesting at first glance and had some great reviews, only to find whole Reddit threads talking about how they weren't well-written and only popular because of "BookTok" (I don't really know much about what that is).

I'm sorry for the long post, and thank you in advance for any suggestions!
