The necrovirus is blamed for Lovecraft's epidemic of madness, for the strange and eldritch creatures that roam the streets after dark, and for everything that the city leaders deem Heretical—born of the belief in magic and witchcraft. And for Aoife Grayson, her time is growing shorter by the day.Aoife Grayson's family is unique, in the worst way—every one of them, including her mother and her elder brother Conrad, has gone mad on their 16th birthday. And now, a ward of the state, and one of the only female students at the School of Engines, she is trying to pretend that her fate can be different.

    In the gleaming steampunk world of Waldron's Gate, citizens aren't meant to dream -- and those who eschew their daily Crumble and dare to do so anyway face madness … and imprisonment in Joffrey Columns, the asylum of towers.And yet, "Dreaming" of a very specific sort is what Eila does every day at the Ministry of Manifestation with her mind hooked to the great engine, called the Blunderbuss. She's accustomed to using her thoughts to Build all that the city needs … but never before have her thoughts been so dark, so laced with demons and shadows. Now those nighttime visions hint at dark conspiracy, a millennium of lies, and a fathomless secret hiding beneath the quiet streets.As Eila follows the boy down the rabbit hole, she discovers secrets that were meant to remain hidden. She discovers an unknown caste of underlings, an unknown place underneath the city. And she learns of her terrible destiny as her own dreams and reality blur, as "what is real?" becomes something uncertain.
