"Music of chance" I'd say, it's a good ride, easy to read, also showcases a lot of his qualities and has a place in my mind forever.

Edit: "Moon palace" is similar in a way. I think those two left the biggest impression in me. They both are probably not the critique's favorites, but perfect as an intro I think.

"Mr Vertigo" was my intro and I think it was a good one as well.

"In the Country of Last Things" is also great, but a bit short for the story arc iirc.

I read the New York trilogy relatively late but these are arguably his most well-received books and I enjoyed them a lot as well.

The other books I mentioned he wrote later, if I'm not misremembering.

The New York trilogy was wonderful

I haven't read all of his books, but my personal favorite was "Invisible". I really loved the style and that the book is told from the perspective of three different narrators with sometimes wildly different interpretations of the same events.

My favourite is "the invention of solitude", but it is not a novel.
