Recursion by Blake Crouch is the most recent and I didn’t know it was time travel till about 2/3 of the way through the book. It got pretty wild towards the end, though I had a tough time getting there.

I mentioned in another comment that Slaughter house 5 was the worst for me because I couldn’t understand it and gave up halfway through.

An older one that I thought was pretty good was All You Zombies, by Robert Heinlein. It wasn’t so much that it had an interesting take but an interesting twist in the story.

This was the worst for me. It’s the only book that I couldn’t finish. It was recommended by someone and I couldn’t understand what was going on.
