The Panama Canal Can Be Shut Down

We take global shipping for granted. But what if it stopped? The Panama Canal has handled a large part of global trade for over a hundred years and was a dream for two hundred years before that. What would it mean if it was closed? Would supply shortages be permanent? Would prices rise further?
With less revenue, would the Panamanian government fall? Would the Great Powers once again find another area to fight over? What would that mean for the rest of the world?

In the bestselling novel ENEMY AT THE HELM, a shadowy group shuts down global trade using all-too-plausible methods. Come join the ordinary family caught up in the extraordinary events that could happen tomorrow!
