Lolita is overrated. Part one is decent enough, but in part two the pacing moves to a crawl and it becomes dreadfully boring. That's actually why many publishers rejected it, not because of its controversial subject matter, but because it's not really that good. Humbert Humbert is also an insufferable, pretentious retard and it's hard to read his inner monologue even during the good parts. You are right in calling it a love story however, that's exactly what Nabokov said it was. People saying HH is an unreliable narrator are coping - HH is totally honest with the reader.

If you want to read an amazing pedophile love story, I cannot recommend Tiger, Tiger by Margaux Fragoso enough. It's about a fourteen year long love affair between a little girl and a pedophile, beginning when she was seven and he was fifty-one. I've read it three times now, and I always read it super quickly because it's incredibly hard to put down. The author had an interest in writing from an early age and worked on this memoir for ten years and it really shows, it is incredibly well-written. And although it is a memoir, she doesn't reflect on the experiences from the perspective of her adult self, but rather only gives her thoughts at the time, meaning it reads exactly like a novel does.

Pic semi-related, it's 9/11 viewed from Union City, where the author lived. Her memoir begins in 1985 and ends right after the anthrax scare in 2001.
