To most people a banana is a banana: a simple yellow fruit. Americans eat more bananas than apples and oranges combined. In others parts of the world, bananas are what keep millions of people alive. But for all its ubiquity, the banana is surprisingly mysterious; nobody knows how bananas evolved or exactly where they originated. Rich cultural lore surrounds the fruit: In ancient translations of the Bible, the "apple" consumed by Eve is actually a banana.

But the biggest mystery about the banana today is whether it will survive. A seedless fruit with a unique reproductive system, every banana is a genetic duplicate of the next and therefore susceptible to the same blights. Today's yellow banana, the Cavendish, is increasingly threatened by such a blight, and there's no cure in sight.

Banana combines a pop-science journey around the globe, a fascinating tale of an iconic American business enterprise, and a look into the alternately tragic and hilarious banana subculture (one does exist) - ultimately taking us to the high-tech labs where new bananas are literally being built in test tubes, in a race to save the world's most beloved fruit.
