Bill Bryson is the world's funniest travel writer, and a master of comic observation. His hugely popular books, spanning topics from linguistics to Shakespeare to the human body, have sold over 16 million copies and been translated into 30 languages, and his 2003 science book A Short History of Nearly Everything won the prestigious Aventis and Descartes prizes.

Twenty years ago, Bill Bryson went on a trip around Britain to discover and celebrate that green and pleasant land. The result was Notes from a Small Island, a true classic and one of the bestselling travel books ever written. Now he has traveled about Britain again, by bus and train and rental car and on foot, to see what has changed—and what hasn’t.

Christmas is the single biggest annual event on the planet, a time for merry-making, over-indulgence, peace, goodwill, and the occasional family row. It’s as comfortable and familiar as a pair of old shoes and yet still glittery and exciting. But what do you really know about it? It’s stuffed full of traditions and rituals that most of us have been observing all our lives without having the slightest idea of where they come from.

Hardly anyone ever leaves Des Moines, Iowa. But Bill Bryson did, and after 10 years in England he decided to go home, to a foreign country. In an ageing Chevrolet Chevette, he drove nearly 14,000 miles through 38 states to compile this hilarious and perceptive state-of-the-nation report on small-town America.

Bill Bryson and his family live in a Victorian parsonage in a part of England where nothing of any great significance has happened since the Romans decamped. Yet one day, he began to consider how very little he knew about the ordinary things of life as he found it in that comfortable home. To remedy this, he formed the idea of journeying about his house from room to room to “write a history of the world without leaving home.”
