Not Everything is Blue And Red

If you are of the Decepticon faction, I suggest you read this. It tells the tale of two femme-bots, twins, as they embark on a journey that pits them against each other, brings them back together, and could ultimately tear them back apart. Told from the point of view of the one who joined the Decepticon faction, you learn the struggles of this femme, which involves love, hate, and the ultimate test of trust.
