Mother Nature has had enough and a day of reckoning is coming, foretold by words that mysteriously appear on the side of a shiny new building. When the reckoning arrives, in the form of a giant sinkhole that swallows the site of a planned development, a large lake, and several miles of interstate highway, the citizens of Opakulla, Florida struggle to understand what is happening. A geologist wants to study it, the developers relish its wild beauty, and the mayor plans to stop it. Only the owner of a local café, who speaks with the Ancients, understands it, and she isn’t telling.
