To my wonderful wife Džana, for her unreserved support and putting up with yet another side project of mine. To my amazing boys, Immy and Rayan, who were curious if I had been writing a "real" book, one that starts with "Once upon a time" and ends with "The End". To my loving parents, Nađa and Sabrija, who devoted much of their lives to their children's education. - N.Š.
