The year is 1901 and our heroine Lumen is a precocious 13-year-old with many questions about her life. Why has her father been gone for years? Why must she learn so many languages and fighting techniques and what's with all the lessons in seafaring? Then an attack on her home by a horde of steam-punk assassins delivers the first glimmer of an answer, when Lumen's savior reveals himself as her grandfather, the legendary Captain Nemo, one of the greatest characters in Victorian science fiction literature. A brand-new world of steam-punk adventure and thrills is about to open up for Lumen as she connects with the grandfather she never knew while together they take on a cabal of evil masterminds, intent on world domination... a world full of heroes and villains from Victorian adventure and fantasy fiction.
