Lolita

The only two things I have heard about this novel is that either a) it's unfinishable because its so horrifying/disgusting, OR b) it's horrifying/disgusting but phenomenally written so worth the read.

I had to DNF it because it was just so damn boring. It starts off strong, and the hoops the MC jumps through to justify his thoughts and actions WAS very well done. But when the MC starts getting what he wants, the story just... sizzles. Like the author just didn't have enough content for a full-fledged novel.
