This book was so dark and disgusting it literally took me months to get through. It's a hard read, but its definitely worth trudging through and digesting. Nabokov is a great story teller, he has an amazing way of putting you in the character's mind. Which in this case with Humbert Humbert, is a horrifying experience. But one that is all too real. And disgustingly, somehow makes you feel a small sense of understanding and pity.  The whole book feels like a crescendo, building up to the downfall of a man who was already at his lowest. 

(Side note, I really like how the last few chapters are written.)
