I just wanted to have the experience of the light novel, I mainly just read the manga or/and watch the anime, so I never knew what it was to read the real source material of certain series. So I went ahead a read, well, got hooked up... when I read light novels I usually spend all my day reading them, they're so much better than the adaptations (manga or anime).
I recommend those that like a certain series based on a light novel that try to read it, at least a couple of chapters, maybe you'll like them =] .
