Book excerpt: Globalization makes it difficult to know where the things you buy come from. Journalist and travel writer Kelsey Timmerman wanted to know where his clothes came from and who made them, so he traveled from Honduras to Bangladesh to Cambodia to China and back. Along the way, he met the people who made his favorite clothes and learned as much about them as he did about globalization itself. Enlightening and controversial at once, this book puts a human face on globalization.
