One determined girl. One resourceful boy. One miracle machine that could destroy everything. After an unexplained flash shatters her world, seventeen-year-old Eyelet Elsworth sets out to find the Illuminator, her father's prized invention. With it, she hopes to cure herself of her debilitating seizures before Professor Smrt - her father's arch nemesis - discovers her secret and locks her away in an asylum. Pursued by Smrt, Eyelet locates the Illuminator only to see it whisked away. She follows the thief into the world of the unknown, compelled not only by her quest but by the allure of the stranger - Urlick Babbit - who harbors secrets of his own. Together, they endure deadly Vapours and criminal-infested woods in pursuit of the same prize, only to discover the miracle machine they hoped would solve their problems may in fact be their biggest problem of all.
