Lolita

It's an interesting read at times, but during some passages it failed to get my attention because of all the detail the author goes into, which sometimes I felt as unnecessary. It does however, accomplish to be more than just a story about a pedophlile, allowing the reader to dig deep into the mind of Humbert and see his reasoning behind everything.
Maybe his malicious act arose more from selfishness and being more delusional than bad per se.
