The first thing to do is to abstract the Club of Incorrigible Optimists. And we discover a book of rare power. I was told that since Koestler few writers had described the existing century with so much talent and lived witness. Jean Michel Guenassia belies a rare quality. It is impossible to summarize such a book that brings us all the possible palettes of a novel, with a rich and smooth writing, humor, realism, rhythmic and intrigues that make us reflect on the century, talking us not necessarily of known events. And we want that Mr Guenassia launches such Zola in the Rougon-Macquart in a company's painting of the last century with such gusto!
