In January 2016, Little, Brown and Company will publish a manifesto about free speech by Stephane Charbonnier, the assassinated editor of the French satire magazine Charlie Hedbo.

The book, Open Letter: On Blasphemy, Islamophobia, and the True Enemies of Free Expression, was finished just two days before Charbonnier—along with eleven others— was killed by two gunmen at Charlie Hedbo’s offices last January, according to The Guardian. The book will include a preface by New Yorker writer Adam Gopnik.

“In Open Letter, Charb’s words are powerful and provocative,” Little, Brown and Company publisher Reagan Arthur said in a statement. “I’m honored to be able to publish this important and lasting work on free expression.”

According to The Los Angeles Times, Arnaud Nourry, chairman of Hachette Livre, parent company of Hachette Book Group, added: “To have journalists and illustrators silenced so brutally for lampooning bullies and extremists was a brazen attack on the fundamental freedom to publish. I am pleased that we will be able to share Charbonnier’s views with readers, and to contribute to the conversation about the insidiousness of religious intolerance.”

For the uninitiated, Charlie Hedbo’s controversial cartoons has drawn out heated discussion among authors and politicians, which, as we reported, sparked debate at last year’s PEN American Center’s literary gala—as well as a petition against its Charlie Hedbo award, and boycott of the event.

Charbonnier joined Charlie Hedbo in 1992, and became editor in chief in 2009.
