Amy Peterson is a self-replicating humanoid robot known as a VonNeumann.
For the past five years, she has been grown slowly as part of a mixed organic/synthetic family. She knows very little about her android mother's past, so when her grandmother arrives and attacks her mother, Amy wastes no time: she eats her alive.
Now she carries her malfunctioning granny as a partition on her memory drive, and she's learning impossible things about her clade's history - like the fact that she alone can kill humans without failsafing... File Under Science Fiction
