LOL I would say its a magical event, but, logical people will look for what's socially broken and seek to fix it, and the fixes are bound to be similar once the problem is identified. So common themes are bound to emerge. The need for a vigilante character comes socially from the repressed nature of modern society with too many rules. The vigilante is across the fabric of society a symbol of dynamic intellectualism which a political order being crushed under its own rules needs for its own good as static intellectualism threatens its well-being.

Good luck with the book. It's tough but worth it. I self-published 'The Symposium' and because it did respectably well, a publisher picked up 'Tail of the Dragon.' But its a crowded marketplace, so unlike the way the world was in Ayn Rand's day, you do have to push and shove much harder to get heard today with all the noise. With that said, its wonderful to have so many options and so much information available to the modern reader---and writer.
