Don't know what happened. Maybe one person just bought 16 books. But as I write this, The Chaos Scenario has its best Amazon rating since its publication. The book usually hovers in the 5000 range, sometimes in the 11,000 range, and I guess there is at least the possibility that it's beginning to get momentum. More likely, it's one bulk order, but either way... There are several million titles sold via Amazon, so this something to savor, and I'm savoring my ass off.
