No one knows exactly when or where it began. A terrifying new plague is spreading like wildfire across the country, striking cities one by one . . . Dragonscale, a highly contagious, deadly spore that tattoos its hosts with beautiful black and gold marks—before causing them to burst into flames. Harper Grayson, a compassionate, dedicated nurse treated hundreds of infected patients before contracting the deadly virus herself. When the outbreak first began, she and her husband, Jakob, had made a pact: they would take matters into their own hands if they became infected. To Jakob’s dismay, Harper now wants to live—at least until the fetus she is carrying comes to term. Convinced that his do-gooding wife has made him sick, Jakob becomes unhinged, and eventually abandons her as their once-placid New England community collapses in terror. But Harper isn’t as alone as she fears: a mysterious and compelling stranger, a man wearing a dirty yellow firefighter’s jacket and carrying a hooked iron bar, straddles the abyss between insanity and death. Known simply as The Fireman, he strolls the ruins of New Hampshire, a madman afflicted with Dragonscale who has learned to control the fire within himself, using it as a shield to protect the hunted . . . and as a weapon to avenge the wronged. . . . The Fireman is coming.
