Un Cri dans le Silence (A scream in the Silence) is a book by the 70's movie, tv and sexy star Brigitte Bardot, it talks about the inmigration, Islamitation and invasion of Arabs and Islamic people to Europe, where they want to build a Eurostan Caliphate.
The nature of their religion and costums, some of them against democratic and western values makes difficult to asimilate.

The book is a favorite for the Ultra right political movements of Europe and France, In the words of Jean-Marie Le Pen, there will be a time in france when we all have to walk looking at the ground, because if we raise our eyes and see some arab in the face they will say, How do you dare to look at me? do you wanna fight?

This book is a necessary to understand the population dinamics of modern Europe, the future of the continent and how that can be related to North American population growth and future.

I would compare this book to Rachel Carson's Silence Spring, a canary in a coal mine that can tell us a lot about the future.
