On January 7, 2015, two gunmen stormed the offices of the French satirical newspaper Charlie Hebdo. They took the lives of twelve men and women, but they called for one man by name: "Charb."

Known by his pen name, Stèphane Charbonnier was editor in chief of Charlie Hebdo, an outspoken critic of religious fundamentalism, and a renowned political cartoonist in his own right. In the past, he had received death threats and had even earned a place on Al Qaeda's Most Wanted List. On January 7 it seemed that Charb's enemies had finally succeeded in silencing him. But in a twist of fate befitting Charb's defiant nature, it was soon revealed that he had finished a book just two days before his murder on the very issues at the heart of the attacks: blasphemy, Islamophobia, and the necessary courage of satirists.

Here, published for the first time in English, is Charb's final work. A searing criticism of hypocrisy and racism, and a rousing, eloquent defense of free speech, Open Letter shows Charb's words to be as powerful and provocative as his art. This is an essential book about race, religion, the voice of ethnic minorities and majorities in a pluralistic society, and above all, the right to free expression and the surprising challenges being leveled at it in our fraught and dangerous time.
