"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 them, Amy wastes no time: she eats her alive. Now she's on the run, carrying her malfunctioning granny as a partition on her memory drive. She's growing quickly, and learning too. Like the fact that in her, and her alone, the failsafe that stops all robots from harming humans has stopped working. Which means that everyone wants a piece of her, some to use her as a weapon, others to destroy her"--Publisher's description.
