There are few things in this world as satisfying as a well-earned, well-executed plot twist. The kind of mind-blowing discovery that makes you turn back several pages just to read it all again.
So, with this in mind, what's the greatest plot twist ever executed in a book?
Maybe your first choice is one that's now become legendary — like the fact that Amy is still alive (and also, ya know, not great) in Gillian Flynn's Gone Girl.
Or perhaps it was a horror story with a few unpredictable twists and turns — like the reveal that the killer was someone we trusted all along in Riley Sager's Final Girls.
Heck, maybe your top choice is something that's widely spoiled now, but shook you to your core when you first read it — like when Snape killed Dumbledore in Harry Potter and the Half-Blood Prince.
