Rogue Element

The Rogue Element Series follows Rogue, an android who was originally created as a decoy. After fulfilling her mission and discovering her individuality, she was allowed to walk off the battlefield so she could forge her own path. We begin in New Zero where Rogue has to rejoin civilization where she'll run into old enemies, violent cyborgs, charming aliens, bounty hunters, a genetically enhanced talking cat and much more.

While this takes place in the Spinward Fringe Universe, you don't have to read any books outside of the series to enjoy it.
