Lumiere

Even in a land of eternal twilight, secrets can't stay in the dark forever. Seventeen-year-old Eyelet Elsworth has only one hope left: finding her late father's most prized invention, the Illuminator. It's been missing since the day of the mysterious flash—a day that saw the sun wiped out forever over England. But living in darkness is nothing new to Eyelet. She's hidden her secret affliction all of her life—a life that would be in danger if superstitious townspeople ever guessed the truth. And after her mother is accused and executed for a crime that she didn't commit, the now-orphaned Eyelet has no choice but to track down the machine that was created with the sole purpose of being her cure. Alone and on the run, she finally discovers the Illuminator—only to see a young man hauling it off. Determined to follow the thief and recover the machine, she ventures into the deepest, darkest, most dangerous part of her twisted world.
