Former rapper of the 2000s, Sinik, came to sign his published book the day before. The fifty copies planned by the booksellers were quickly sold out.

For several hours, the signing session will reflect this image: a succession of inhabitants of the Les Ulis districts, proud to see or see again "the child of the country who succeeded and who has not forgotten LesUlis" The book is published by Faces Castés, “A wonderful era”, taking the title of one of his hits.
