Books With Psychological Elements

I dunno if this qualifies but when it comes to Stephen King's book, Misery, I more remember the subtle nature of Annie's abuse rather than the big moments, like when she hacks off his foot with an axe. The moment that always comes to mind: early on, she starts ranting about how she read the manuscript for Paul's latest book and doesn't like it. While ranting, she gets so worked up that she flings a bowl of soup where it lands against the wall and stains it. Then she's like, "Oh look at what you made me do!" and makes him wait in agony while she very slowly cleans up the mess, knowing full well that he's become addicted to the pain meds she's given him. It's no wonder that Paul comes to envision her as a goddess. Like a goddess, she can and will inflict pain on him for no real reason and holds incredible power over his life. The only power Paul holds is the power he has a writer.

But if you're into King, The Girl Who Loved Tom Gordon, is also good in that it never really answers whether all the horrible stuff the poor kid is seeing is the product of fear, hunger, and sickness, or something supernatural. It's a simple story--kid gets separated from her family while on a hike and has to survive on her own in the woods--but a surprisingly effective one.
