I felt like challenging myself and challenging my readers with something darker and heavier. I don't know how to explain it, because I'm not a political person. I have two political stories, and that's it: 'Human Diastrophism' and 'Poison River.'
I always felt I was living in two worlds. One was the Mexican world, because nearly everybody I knew, relatives and cousins and kids in the neighbourhood, were Mexican. Then school was a different world. It was ethnically mixed.
