Does anyone else try to know as little as possible about a book before reading?

It's the only time I don't actually. For movies and tv series I stay far away from info as to not spoil it. For books; however, I find out as much as I can without discovering spoilers, because I don't want to dedicate the time required to read on something that I won't like.

I do have exceptions though for certain authors that I will read anything they write.

No, i actually try and figure out a good bit about it so I know that I will like it. I even spoil myself on purpose sometimes - even endings to a degree. Sometimes I try and fly through to find out and miss out on some of the awesome nuances that are my favorite parts.

For authors I think of as a known commodity, I will usually just buy and read. But i'm not afraid of spoilers so I still will google something I am curious about in the middle of a book and that kind of thing sometimes.

Take the Dune series for example - I read up on the sequels a bit so that I could decide if / when I wanted to read them. I know generally what happens in the last few books, but I am still excited about reading them - even moreso since I wasn't a huge fan of Children of Dune, but I really like the overall concepts of where the series is going in the last couple.
