I was wondering if anyone had recommendations for good books that focus on the period anywhere from the latter portion of Franco's regime through the establishment of a new constitution and democracy (or even further).

I've read Mark Kurlansky's The Basque History of the World, which was great for that perspective. However, I'd like something that delves a little more into the politics and actual mechanics of that transition process. The little bit of information I've been able to find has been absolutely fascinating, but I was hoping to fine a more complete source that's accurate and enjoyable.

Thanks for your help!
