Amy Peterson is a five-year old self-replicating android who lives with her synthetic mother and human "father." Her struggles might be that of any super-intelligent youngster whose body and mind mark her as different than her schoolmates, but then her grandmother, Portia, appears at her kindergarten graduation and attacks her mother. Amy's intervention leads to a startling result: she eats her grandmother and, in doing so, stores a self-aware fragment of Portia within a memory partition. She soon learns that Portia has a peculiar trait–she lacks the failsafe the prevents Vns from harming human beings. Now Amy must flee for her life while discovering the truth about herself and her inheritance.
