Girl Genius is the signature work of Phil and Kaja Foglio, a gaslamp fantasy comic that has been running since 2001. Set in an alternate version of nineteenth-century Europe where “Sparks,” people with a supernatural talent for mad science, have reshaped civilization, the series follows Agatha Heterodyne as she discovers her own Spark abilities and gets caught up in a continent-spanning conflict.
The graphic novel collections gather the story into volumes, from the early Beetleburg adventures through the Airship City, the Circus of Dreams, and the Siege of Mechanicsburg. The series has won three consecutive Hugo Awards for Best Graphic Story and built a loyal readership through its combination of adventure, humor, romance, and inventive worldbuilding. The art is colorful and expressive, and the cast of characters is enormous, featuring mad scientists, sentient constructs, warrior princesses, and scheming aristocrats. Girl Genius rewards close reading, as background details and throwaway gags often become important plot points volumes later.
