Authors and Websites

  • Recommended by: ironinfidel, madanimalscientist
  • Comments: The author is extremely talented, with a beautiful style and an excellent grasp of the characters and their relationships (and her Technobabble is great too). Writes largely on the relationship between Agatha and Zeetha and the OT3 of Agatha/Gil/Tarvek, but also about the first generation characters and other relationships; there's something for every GG fan. Varied ratings, from G to R.
    • Seconded. Excellent grasp of the relationships and dynamics involved. Can and will make you cry.


Stories focused on the family and the friendly relationships of the cast. Plot-focused stories or light day-in-the-life stories. Pretty much anything that isn't focused on romance.

  • Status: Complete

  • Recommended by: PK
  • Status: Complete
  • Synopsis: Maxim becomes a Jäger; the Storm King and the Heterodynes maneuver against each other on and off the battlefield; and Otilia is thrown into both cultural and internal conflicts.

  • Recommended by: PK
  • Status: Complete
  • Synopsis: Klaus Wulfenbach's parents were, as the Secret Blueprints tell us, Sparks who ran their holdings well and used their gifts to benefit their people... and had three sons, but the other two haven't been seen in years. Klaus is a construct. This is the story of Katherina Wulfenbach, and how it happened.

On Her Undying Majesty's Secret Service by ImperialGirl
  • Recommended by: PK
  • Status: Complete
  • Synopsis: Ardsley Wooster, British Intelligence, has an important assignment in Paris—ingratiate himself with the heir to Baron Wulfenbach. But Ardsley's not the only one in Paris with a secret agenda.
  • Pairing: Ardsley Wooster/OC
  • Notes: Has a sequel, The Clank with the Golden Gun.
  • Comments: Girl Genius meets James Bond. Featuring Ardsley Wooster's adventures before the comic begins. The other lead is an original character whom the author unabashedly writes as both very human and precisely as awesome as she ought to be. Lots of action and plotting, lots of fun for the readers.
    • The sequel is just as good as the first, but fair caution — it's not abandoned (I checked!), but it is a long-term WIP and the author is rather busy.

  • Comments: A sweet narrative, featuring Agatha Clay learning a great deal more about the jagerkin then she would ever have expected, and Jorgi getting laughed at for writing, among a great deal of other things.
