Along the way, about certain things, you realize, "I don't know anything about this." You think, "Is this going to sound ridiculous?" So I pestered more than a hundred different people over the course of the book. And when I finished the book I gave it to six or seven trusted readers, who are always the same, but I also gave it to a brother of mine who's a doctor and I asked him to read it, and he was very helpful. It's good to have a group of trusted readers. As my kids have grown up, they've joined this group.

I take all my characters very seriously - the main, secondary, and supporting characters. Even if they only appear once, they still need to have their own life. Some characters are absent literally but at the same time very, very present.

For someone like you who's a British citizen this might seem strange. How can you ban a language? It turns out that you can. During the dictatorship it was illegal to speak Catalan. This is an experience that we Catalans have all had to varying extents. Some more tense than others, but it's something we all share.

Research is necessary. However, you need to make sure you don't fall into its trap. You need to have time left for writing. To avoid the trap, I just throw myself into the abyss while at the same time being aware that if I'm dealing with information I don't know enough about, I have to go to someone and talk about it.

There were many books in my parents' home. I'm from a family of five children and we were all readers. And so by the time I left home, I had already read many books, and I was very interested in reading more. That was when I started to have the desire to write. But it wasn't like a divine apparition with angels and seraphins on high. Not for me, at least.

Everywhere you go you find readers who are interested, even though the story takes place here in this very neighborhood. It doesn't matter that it takes place locally if the intention to make it universal is there. That's what I strive to do.

I'm always reading, and you learn a lot by reading. When I was twenty-five, I read a lot, but didn't have much reading behind me.
