The first two that came to mind have already been mentioned. (Wind Up Bird Chronicle and House of Leaves)

Annihilation - Wild ride by Jeff VanderMeer and I loved it

The Cat Who Walks Through Walls - Not what I was expecting from Heinlein after reading Starship Troopers, nothing made sense or even seemed remotely connected

I was 90% finished with this one before losing my copy. I picked up another but am struggling to resume reading it since the friend who introduced me to it passed away

I was going to mention this title. It was the first that came to mind
