It happens all too often: you're reading a book, getting steadily absorbed in a plot, and then realize, to your dismay, that it's exactly like a million other plots you've read before. Congratulations, you've found another plot cliche.
These kinds of tropes and cliches bother me perhaps more than they should. When I read a book, I want something new and different. It doesn't have to exactly revolutionize fiction, but it shouldn't remind me of every other book I've read in my life, either.
That's why I always love it when I come across a book that seems like it's going to plant itself smack dab in the middle of cliche-land, and then ends up being completely different. One example I can think of is Fair Coin by E. C. Myers - you think it's going to be a stereotypical "wishing" book but then whoa, plot twist.
What other examples can you think of?
