This is the home of the fanfiction novel, Distorted Reflections, by lizardbeth_j and Lori Wright.
While searching for the Lost City, SG-1 is trapped on a strange and frightening alternate Earth. Fifteen years ago a plague decimated the Earth, killing the adults and leaving the children to fend for themselves. Now those children have grown up, and a war is brewing over who will control the future. Jack, Sam, Daniel and Teal'c find that they must fight, risking everything, if they hope to find a way home.
This is a crossover with the t.v. series Jeremiah; however, no knowledge of that series is necessary. (you can read it as a new world, populated by well-developed OCs, really)
Rated R for adult situations, violence, and language
Gen. No pairings.
Features the entire season 7 team, including Jack, as well as many SG-1 characters in an alternate form, and all of the characters of Jeremiah.
