Earlier this year, two gunmen shook the global news cycle when they walked into the Paris offices of satirical magazine Charlie Hebdo and opened fire. The attack killed 12 staff members, including editor-in-chief Stéphane Charbonnier (known as “Charb”), whom the gunmen reportedly called out by name. In a strange coincidence, Charbonnier had just completed work on a book two days before his murder. Now, that book will be published as Open Letter: On Blasphemy, Islamophobia, and the True Enemies of Free Expression from Little, Brown next year.

“The murder of Stéphane Charbonnier and his colleagues at Charlie Hebdo was a tragic moment for France, and for the world,” Hachette Livre chairman Arnaud Nourry said in a press release. “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.”

Open Letteris currently set for a January 2016 release.
