A noblewoman and an airship pilot fight zombies, mad scientists, and more in this steampunk adventure series debut by the author of Iron Axe. A bizarre strain of zombies roam the streets of Victorian London, infecting all they touch with the Clockwork Plague. While most victims die painful deaths, a few become Clockworkers, geniuses who create the greatest inventions of the age—right before going insane. The plague has also taken its toll on the life of twenty-two-year-old Alice Michaels. After her mother and brother die from the disease because of her, she feels obligated to ensure her father’s happiness. Unfortunately, that means ignoring her passion for automatons and instead, pursuing the wealthiest man possible. But when zombies attack Alice’s cab, being tied down in a loveless marriage is the least of her worries. She is quickly swept up into a secret organization chasing down Clockworkers—and into the arms of Gavin Ennock, a former airship cabin boy and talented fiddle player. Together they will navigate a political conspiracy that threatens to consume their country and the world . . . “If you love your Victorian adventures filled with zombies, amazing automatons, steampunk flare, and an impeccable eye for detail, you’ll love the fascinating (and fantastical) Doomsday Vault!” —My Bookish Ways “Harper creates a fascinating world of devices, conspiracies, and personalities. . . .
