In 1844, thousands of Americans gave away their possessions certain the world would end on a set date. When it didn't, they coined the name for what followed. They called it the Great Disappointment. This book borrows it for a pattern still repeating. It is happening again, dressed as a countdown. A tablet claims to predict a pole shift for March 2029. No excavation, no translator, no researcher behind it holds up. But the question it raises outlives the fake. If something like that did happen, would we be ready? And would we be able to tell whether it was real or manufactured, and whether this again led to another great disappointment? But a second Great Disappointment does not need a fake tablet to arrive. This one is real. It has been building for thirty-five years, since the peace promised at the end of the Cold War. It never had a single morning of its own. It has been arriving in pieces instead, each one easy to explain away on its own. Add them up, and the pieces total a pattern with a name history already gave it. This book names it directly.
