A group of young Canadians is out on a field trip in the Louisiana swamps when an epidemic breaks out, unlike any the world has ever seen. The highly contagious virus turns people into seemingly mindless creatures, monstrous in appearance and inhumanly strong when provoked. To halt its rapid spread, the U.S. government walls off the area. When one of their own succumbs to the disease, the kids are trapped in the contagion zone. To survive, they must fight bloodthirsty militias and infected creatures alike, as they hold out hope they can find a cure for their friend, before he becomes a menace to them all.

A planetwide virus. The collapse of civilization. A class of young Canadians caught on a field trip in the ruins of Louisiana, fighting desperately to stay together, and stay alive. They've managed to escape the quarantine zone, but that just means they're in terra incognita. The infection has turned one of them into a misshapen monster: a gentle giant nevertheless capable of great violence, that various warring factions of humans are out to kill or capture. In this second volume, Jérôme Hamon and David Tako deepen their pulse-pounding and profoundly humane portrait of a fearsome post-viral landscape.

A viral pandemic. Cities in lockdown. Humankind hopelessly divided into warring factions. Guns in the streets and every man for himself. In the third episode of Green Class, the stakes have gotten even higher. Still trapped in the post-apocalyptic hell-swamp of Louisiana, our band of young Canadians finds itself neck-deep in something far murkier and beyond mere science when the teens stumble across the true source of the rampant plant zombies besetting them: a book called the Necronomicon. With secret experiments to open an interdimensional portal to the elder gods, the end times take on a whole new dimension, calling to mind the uncanny worlds of Lovecraft.

With the countdown begun to the appearance of the Great Old Ones, the end of all humankind ticks ever closer. Creators Hamon and Tako ratchet up the action as our ragtag group of teenaged heroes tries to sort good from evil, friend from foe, while saving their friends and the world as we know it. But do they have any hope at all against the secret, federal, and cosmic forces arrayed against them? Find out in this thrilling sequel.
