What book subverted all your expectations?

[StevenSwift]

Whether it's the plot itself, the quality of writing, or anything else about the book, have you ever read something that just had you going, "Wow...that was NOT what I expected."

I felt this way when I read Wyrd Sisters for the first time. I think I was just expecting a run-of-the mill fantasy. Little did I know that I was about to enter into the Upside Down version of our world, as written by Sir Pratchett -- so it's not quite upside down but flat and on the backs of four elephants, which are, in turn, on the back of a giant tortoise.

I was in eighth grade and it was the first time I had been introduced to footnotes as a way for the author to speak to the reader! The idea of meta, of a wry comment, a satire all within a STORY that kept me engaged...it was so fun! I devoured all the Discworld novels after that, as well as works of other writers in a similar vein.

I'm a writer now and Sir Pratchett's influence is very evident in my work. Needless to say Wyrd Sisters subverted my expectations in a life-changing way.

Any book that had you shook? In a good way? Bad way?
