Lolita

I love how Nabokov has created the internal world of the main potagonist Humbert Humbert who clearly is conflicted with himself. The dead of his first girlfriend clearly leaves a mark on him making him and he keeps his passion for young girls even at a later stage of his life. The book is an entertaining mix of comedy and tragedy.

Considering that English is not the native language of Nabokov, the use of it in this book is brilliant.
