may I propose Boris Vian's "The Foam of the Days"? It's a beautiful love story in surrealist writing
However, on amazon I found it as "The Foam of the Daze" (?!) and one of my fellow Romanians, I see, considered the English translation rather poor, after having read it in French (the original) also.
Anyway, it's one of the most touching love stories I have ever read and it literally brought tears to my eyes. Not to mention the stunning images and the metaphors adorning the writing from beginning to end.
So please consider it.
ps - I vote NO for Lolita. I read it in school, I saw one movie, the subject already makes me sick. Imho, it's not a love story, it's the story of an obsession, not to mention the grown-man-seducing-the-immature-underage-girl theme. I don't like it.
On the same subject, you could also read Marquez's "Memory of My Melancholy Whores"
some of the descriptions in there could count as really beautiful had they not been about a decrepit old man and a 14-year old girl
Now you can start throwing stones
