Fun books like Ready Player One, but good

I just finished Ready Player One. I can't say I didn't enjoy it but the style of writing was a tad too childish and one dimensional for me.
I'm in a stage where I really want to go back and enjoy reading.
Not to the level of needing something really cheap like a thriller or a Harlan Coben book.

Another good example is Dark Matter by Blake Crouch which I really liked.
I also recently read "We have always lived in the castle" and loved it after pushing through the beginning.
Thanks a lot 🙂
