Sparks are Mad Scientists. For many years they terrorized humanity until Baron Klaus Wulfenbach conquered them all and restored civilization under his iron thumb. His job was made a little easier due to the fact that most of them didn’t last long after their genius emerged. This was because, on a whim, they often added poisonous fangs and a complete indifference to human life to their first inventions, which usually eliminated the problem immediately.
Agatha H. is a Girl Genius and a Spark, but she doesn’t know this because whenever she concentrates on anything she gets a terrible headache and it always comes out wrong. It turns out that this is a good thing because by the time she discovers why, the urge to add the fangs has passed.
Looking forward to the rest of the series.
