On a Parallel Earth, my double is the only daughter of a powerful family. This family controls half of the Earth, and another one controls the other half.Profits come from mining colonies on Venus and Mars. My double was to marry the son of the other family, to bring peace after a century of almost bitter rivalry, only she escaped the palace with friends from lower class families loyal to hers for a night, something she did often, and was killed in a fight with a street gang.
The family would dispatch scouts to parallel Earths to find a suitable double for her from the many doubles that exist on parallel Earths, and after several unsuitable finds, they lock onto me, on this Earth. With my parents both deceased, and working long hours, the team judges me suitable to take the place of the rebellious princess, and takes me to their parallel world.
If this appeals to anyone, let me know.
