Acheron Every last character from Acheron, by Sherrilyn Kenyon.
Never read that book. I wasted 800 pages of my life, and God only knows why.
Let's see...
Actually, I would say Bella from Twilight. She's the stupidest of them all.
Jamie, from Outlander by Diana Gabaldon. I did not like him.
I'm surprised that I can't think of more. I guess that this is because when I don't like a book, I usually put it down and give it away. I won't continue reading if I don't like it. Sometimes I keep reading, when I really shouldn't.
