This was a pretty fun read. Through most of the story, I found myself a little bit in awe of Nabokov and his ability to make a book about a pedophile's obsession so entertaining and even funny. It's a literary hat trick.
That said, it gets a tiny bit tiresome towards the end. Humbert Humbert is amusing as a laughable, priggish fop, but I got a bit fatigued with his cleverness. I guess Lolita did, too.
However, some of the sentences are beautifully crafted: "The sad eyes of unsuccessful blondes," or "I was weeping again, drunk on the impossible past."
