Along the way you’ll meet colorful characters like the feathered-serpent god Quetzalcoatl, who gave chocolate trees to the Aztecs; Henri NestlÔe, who invented milk chocolate while trying to save the lives of babies who couldn’t nurse; and the quarrelsome Mars family, who split into two warring factions, one selling Milky Way, Snickers, and 3 Musketeers bars, the other Mars Bars and M&M’s.
