The Roboticist of Versailles book 2
Paris 1881: the new Naturalist king of France has banned all technology. Adelaide, formerly a high-ranking Scientist, is in hiding from his enforcers at the Hotel-Dieu, a Paris hospital run by nun-nurses with strange powers. She’s driven to use her forbidden scientific skills to help the Augmented veterans even though she faces execution if she’s discovered.
The Vitruvian Mask continues the story of Adelaide Coumain, the Roboticist of Versailles, that began in The Archimedean Heart but can be read as a standalone.
