Sparkgate: Agatha and the Grasp of the Serpent God by Samarkand
Summary: There are nigh infinite variant timelines surrounding that of the Stargate universe we know. Most turn out badly as one choice or another dooms Earth. One, however, is unusual in that a chance refugee from another branch of Earth's many alternate universes provides some...unexpected effects. There may be maniacal cackling. There probably will be tesla coils. There most certainly will be elegantly crafted death rays. Discover what happens when the Milky Way Galaxy discovers what the Spark of mad genius can do. Steampunk and science fiction collide in...SPARKGATE! FOR SCIENCE!
Warning, it's a work in progress.
