Anyone planning a trip to Andorra should read "Dots on the Map" by Colin Leckey.  It's the tale of the author's trip to Europe's seven smallest countries - the Faroes, Liechtenstein, San Marino, the Vatican City, Monaco, Andorra and Gibraltar. 

The highlights of his trip to Andorra include relaxing in Europe's largest thermal spa at Caldea, getting hopelessly lost and laughed at by Dutch bikers on a walk near Ordino, and inadvertently gate crashing a visit to the Andorran Parliament by a party of French pensioners.  There are some fascinating insights into the history of the tiny republic in the Pyrenees - learn how the Heads of State ended up being the President of France and an obscure Spanish bishop, and all about the short-lived reign of King Boris the First.

The book is available on Amazon for around £8.99, and there's a "search inside" facility so you can read more before buying.
