London, 1892. Like most children in the working-class town where she lives, Indira works the coal mines every day without protest. But when her little brother Eliott disappears, nothing matters anymore... She embarks on a desperate quest to find him and discovers that he is not the only child to have mysteriously disappeared. All clues seem to point to the same person: Cathleen Sachs, the wealthy owner of the coal mines. But why would she kidnap these children? From the acclaimed writer of NILS: THE TREE OF LIFE and animation designer SUHEB ZAKO (Netflix's "ARCANE"), this adventurous tale of magic and mystery leaps off the page like an animated feature in print.
