Mud, Ice, Iron- paperback

The modern world runs on a comforting lie: that trade has gone weightless, digital, and frictionless. It hasn't. Every product in your life is still dragged across an ocean, flown over a frozen tarmac, and sorted through a century-old rail yard — forced through a handful of narrow passages where the whole system can seize.

Mud, Ice, & Iron takes you inside those choke points: the single inch of water under a ship's keel in the Panama Canal; the midnight congestion of the Malacca Strait; the sub-zero weight-swap that keeps trans-Pacific air cargo moving through Anchorage; and the frozen switches of the Chicago rail hub, where a quarter of America's freight changes hands. It traces how four decades of stripping every buffer out of the supply chain in the name of efficiency built the most productive — and most dangerously fragile — commercial machine in history, where a drought, a blocked strait, or a software glitch can empty store shelves a continent away.

Part reported thriller, part field manual, written from inside the trade underground, it closes with a clear-eyed roadmap for rebuilding the margin of safety we threw away — before the next break does it for us.
