The world's greatest importer and exporter, the European Union is an economic heavyweight with a GDP even larger than the US. But how much do we really know about the nature and aims of the EU, the benefits and costs membership brings, and its impact on peoples' everyday lives?

Featuring the most up-to-date assessment of the EU, its inner workings, external relations, and likely future development, this is the perfect introduction for anyone seeking to better understand European integration and what it means for Europeans as well as the rest of the world.
