Read it while you're young enough...
...for it not to be too weird that you found that book to be the hottest thing since toasted bread. As a 15 year old I read a book about a girl who, in theory, at any point I could be going out with. Compared to the likes of Crime and Punishment this is short and easy to read.
The story is rad. It touches on everybody(?)'s innermost worry at that age other than their sexuality, namely "That girl who is about 12 looks awfully pretty. But she's 12. Oh no, I must be a paedophile (it's a hebephile, anyways)." This book just makes you more worried. Humbert is a creep, but at this stage you wonder if you could become just like him. The book is brilliantly intense for the first half but once things get a bit more spread out in terms of locale and time period I found it to lose its power in the middle. It gets better again quickly. Especially the travel montage. It did not further the plot and you know it's true.
My first sentence was a little misleading. There is sex, but all of it is implied, your dirty thoughts filling in the blanks, *wink*? The writing is incredible, with many various references but a solid display of advanced literary techniques like giving the verbs in order to swap a more dramatic or, in this case, jarring, effect. Okay, that was a terrible attempt, it is used properly in the book.
I enjoyed the whole contrast of the beauty of the outside appearance of America versus the seediness of within it and the way that it was all very subtly led in. Because of the way Humbert is the narrator we get a very stilted view of who Lolita really is which helps us to feel worried as to whether the entire concept of her kidnapping and regular rape is really just "no biggie" for her. Nabokov realises this, and so every so often he makes a comment suggesting how wrong Humbert is. I liked especially the time in which Lolita thinks that Humbert is asleep and starts to cry. No, I found it very distressing, but you know what I mean.
The conclusion is satisfying if you worked out all of this Quilty chase business. I had no idea what was going on which made it less so. Make sure to read the preface because it helps resolve plot points, and again afterwards, just in case you missed something.
It is a very good book. It is sexy, but don't be put off by that, because it is both a classic and readable - a rarity.
