Carbon And Silicon h/c back

Carbon and Silicon are the first of a new generation of robots meant to care for the aging human population. Raised in the protective cocoon of a laboratory, they are eager to discover the outside world but are dramatically separated during an escape attempt. Lost and alone, they will gather three centuries' worth of experiences, observing the last gasps of humanity facing the ecological, economic, and social disasters that they themselves have created. Faced with this declining world, will Carbon and Silicon manage to find their place?
