Sine Qua Non publishing house was founded in mid-2010. The company’s idea which has been motivating its founders (Przemysław Romański, Łukasz Kuśnierz and Michał Rędziak) is to publish the books „with passion”. Some people are passionate about football, others love movies, while some other people are interested in contemporary art or adore reading engrossing novels. A book is the factor which helps to develop passions and share them with others. Sine Qua Non works according to these ideas. Among the books published one can find sport and music biographies, comic books, novels and other books which have been created out of passion.
