For me it was Gerald’s Game by Stephen King. I think it’s a fantastic novel with amazing character development. The main character is extremely realistic and well written. Despite the seemingly silly premise, I was invested throughout the entire thing. The main character’s development is really what sells it for me.
That being said, I am absolutely not reading it again anytime soon. There are two scenes in particular(if you’ve the book I’m sure you know) that managed to make extremely uncomfortable, mortified, and disgusted. My biggest fear is being trapped and helpless, so this book really got to me. Fantastic book, I’m never picking it up again.
Either that or Lord of the Flies… Dear God.
Ah, Gerald’s Game. I was quite into Stephen King’s books before it, back then I had read a bunch of them, some more than once. After reading Gerald’s Game I couldn’t get anywhere near a book of his for five years or so, that’s how horrified I was by one specific scene (>!how she got out of handcuffs!<). It’s been fifteen years since I read it and that scene gives me the creeps still.
So yeah, I can’t remember how much I enjoyed it at the time, but if there is a book in the world I will never, ever get near, then Gerald’s Game is it.
