I was ecstatic when, after years of effort, a Spanish publisher was found for my Joanna Stafford novels. My main character is half-Spanish, after all. :) It sets her apart in Tudor England, makes her special. Joanna's mother, a Castile-born maid of honor who came to England with Catherine of Aragon, appears in The Crown. And in The Tapestry, the Holy Roman Emperor himself, Charles V, ruler of Spain, enters the plot, along with a few of his Inquisitors.
The publisher, Siruela, is an excellent one. Their chosen title is El Caliz, which is close to the English of "the cup." The catalog page is here.
I'm always intrigued by the covers designed in other countries. This one is, I think, quite interesting.
The Spanish edition of The Chalice, now on sale.
