Boneshaker (The Clockwork Century, #1)

In the early days of the Civil War, rumors of gold in the frozen Klondike brought hordes of newcomers to the Pacific Northwest. Anxious to compete, Russian prospectors commissioned inventor Leviticus Blue to create a great machine that could mine through Alaska’s ice. Thus was Dr. Blue’s Incredible Bone-Shaking Drill Engine born. But on its first test run the Boneshaker went terribly awry, destroying several blocks of downtown Seattle and unearthing a subterranean vein of blight gas that turned anyone who breathed it into the living dead. Now it is sixteen years later, and a wall has been built to enclose the devastated and toxic city. Just beyond it lives Blue’s widow, Briar Wilkes. Life is hard with a ruined reputation and a teenaged boy to support, but she and Ezekiel are managing. Until Ezekiel undertakes a secret crusade to rewrite history. His quest will take him under the wall and into a city teeming with ravenous undead, air pirates, criminal overlords, and heavily armed refugees. And only Briar can bring him out alive. Early in the American Civil War, rumors of gold in the Klondike have brought would-be prospectors to North Americas Pacific Northwest. Anxious Russian investors commission American inventor Leviticus Blue to create a machine which can mine through the ice of Russian-owned Alaska. Blues Incredible Bone-Shaking Drill Engine (or Boneshaker for short, named after boneshaker bicycles of the era), instead destroys several blocks of downtown Seattle and releases a subterranean vein of blight gas that turns anyone who breathes it into a species of zombie.
