what to read next:
If you enjoyed Brave New World, you should definitely read it's moral conterpart: Huxley's "Island". This is maybe my favourite Huxley book because it brings in some of his eastern influences and melds the with his own answers; a version, noncynical, of utopia responding to the dystopia of BNW.
After that you should move on to Hesse's steppenwolf (I see mentioned above) and Siddartha. You're gettin there.
