Earthchild: Doris Piserchia

She called herself Reee and she was the last human being on Earth. This was the one thing she was sure of. Earth was not a dead planet, not by a long way. There were all manner of strange plants and bizarre animals, and there were the blue boys who insisted they were human, but she always set fire to them. There was, however, Indigo, the all-devouring protoplasmic ocean that was literally gobbling up everything in the world. And there was the enigmatic Emeroo to whom she owed her continued existence. There were also the so-called Martians - humans who had fled to Mars and who only came back to Earth to look for survivors and vent their futile furies on the inhospitable homeworld...Cover art by Michael Whelan.
