As a writer, I have to pop in and say this in defense of one of my all time favorite authors ever, Nabokov.
In "Lolita", Humbert Humbert tells the story. He is the narrator.
If a man had sex with a 12 year old girl and told you that she seduced him, would you believe him? It's actually a very common claim for pedophiles to make. You aren't meant to believe Humbert Humbert any more than you would believe any such man. There are huge clues in that book to just how much damage that man has done to that little girl.
Nabokov uses a literary technique in this story called a suspect narrative or a dubious narrative. It is a work of genius and people really misapprehend it because they take Humbert Humbert at his word.
Hijack over.
