Underground Protestantism in Sixteenth Century Spain: A Much Ignored Side of Spanish History

To me, this sort of tomes are very important. My fellow young people in the continent, think that Geneva is the center of the universe when it comes to the Reformation, and some think that Scotland is the real center of the Reformation.

While not denying their contributions to the cause, There was a Reformation in Spain as well, as there was in other places. 

Here it's the description of the book:
Spain and the Reformation seems an awkward combination. Spain retains the image to be a thoroughly Catholic country, where the Reformation never had the opportunity to set foot at. Frances Luttikhuizen points to another direction. He shows that their was a protestant church on this part of the Iberic, but that it was concealed for the outside. Luttikhuizen explains, reveals and concludes that this much ignored page in the history books of Spain is relevant for the understanding of the Reformation worldwide.

I am hoping to get it some time. Thanks to zwinglius redivivus for the heads up. You can find the link to the book here and here.
