Spanish colonisers settled on North-American territory. Half a zentury before the British reached the other side of the Atlantic, nevertheless, it is the British who shaped this land and founded the United States of America. Today, this country is once again home to "yankees" and hispanos. Gringolandia is a portrait of the USA from the early 1970s up to the beginning of the 21st century. The book outlines the continuous battle between Republicans and Democrats for the political and economic power of the American neo-empire.

Based on the author's own American experience, especially during the five years he was a foreign correspondent in Washington D.C. for El País. In the eighties, Vilaró proposed that the "colonies" have a vote in the presidential elections, and today, twenty years later, he argues that Europeans should have a right to vote for those who involve us in pre-emptive wars, without revealing the objectives.

The characters the author has met throughout the United States will help the reader understand and analyse the complex and influential structure of this North-American giant, covering political, economic, social, cultural aspects as well as the bi-lateral relations with Spain.
