My recommendation is to read Stephen King.

Here's a website that lists all his books in publication order. I'm reading them from earliest to most recent (I'm at about 1990 currently): https://www.deadgoodbooks.co.uk/profile-stephen-king/

He's a good storyteller, he uses colloquial language, and even as a native speaker I always learn new words with every one of his books he writes. For example, I learned from reading the Tommyknockers that the word "depend" can mean "to hang from", as in "The moss depended from the branch of the tree".

Also, I think I've only seen one typo in all the books I've read of his so far. I've read about 20 (all of them up to Tommyknockers), and there was one spelling error somewhere in Christine. So it's extremely well-edited, well-proofread.

Reading on kindle paperwhite is amazing because you can long press any word to get its definition. So much faster than trying to look it up in a dictionary, even a digital one.

Really though, any fiction is good for that. Fiction will fill in an intuitive understanding of at/on/in for example, simply by presenting each word hundreds of time in correct context.

The rules we write down to describe grammar aren't really how it's defined; we just write those down for fun. Grammar is really defined, and learned, the way machine learning works: tons of examples. I couldn't tell you the rules for those words, for instance. I could try, and come up with something, but it wouldn't convey everything I know because the knowledge is unconscious.
