Doris Piserchia’s 1977 Earthchild is a stand-alone science fiction novel.
One day, while Reee — two syllables — and her mother were foraging for food in the strange and hostile ecology of a far future Earth, Reee’s mother fell for an obvious trap and was carried off by Martians. As she was just four years old, Reee should have perished at the teeth and claws of bizarre predators. Fortunately for Reee, Emeroo intervened.
But first! Some necessary background exposition.
