The Second Journey of Agatha Heterodyne continues the Girl Genius story after the Siege of Mechanicsburg, as Agatha and her allies head into new territory. Beginning with “The Beast of the Rails” (2015), this sub-series follows the same characters and ongoing plot, with Agatha traveling beyond the familiar settings of the first series.
Subsequent volumes include “The City of Lightning” (2016), “The Incorruptible Library” (2017), “Kings and Wizards” (2018), “Queens and Pirates” (2020), and “Sparks and Monsters” (2021). The Second Journey expands the world of Girl Genius into new locations and introduces new factions and threats. For readers following the series, this picks up right where the main sequence left off.
