Amy Peterson is a von Neumann machine, a self-replicating humanoid robot.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, little 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 the failsafe that stops all robots from harming humans has failed Which means that everyone wants a piece of her, some to use her as a weapon, others to destroy her.
