I'm a huge fan of Spain, Spanish culture and food and have just finished reading this wonderful novel set in London and Spain.
It's The Olive Groves of Belchite, by Elena Moya Pereira and I enjoyed it tremendously, a truly gorgeous read that I highly recommend.
When I've read a book and enjoyed it so much I usually Google the author. Not only did their personal website pop up but she goes on to explain all about the book, why it was written and even pinpoints the locations it uses. Wonderful stuff indeed.
