Boneshaker

Inventor Leviticus Blue creates a machine that accidentally decimates Seattle's banking district and uncovers a vein of Blight Gas that turns everyone who breathes it into the living dead. Sixteen years later Briar, Blue's widow, lives in the poor neighborhood outside the wall that's been built around the uninhabitable city. Life is tough with a ruined reputation, but she and her teenage son Ezekiel are surviving--until Zeke impetuously decides that he must reclaim his father's name from the clutches of history
