Este é " O Livro Verde ", um romance de 1986 de Jill Paton Walsh
Possui plantas cristalinas (que você pode ver na capa do livro) e um tema de fome;
Refugees from the dying planet Earth, they, along with other ships, have been sent into space in the hope that some of them will survive to continue the human race. But the success of Shine remains doubtful as crops fail and provisions brought from Earth dwindle.
Even the excitement surrounding the hatching of the giant moth people from the "boulders" in Boulder Valley doesn't make the group forget the hopelessness of the situation. It isn't until Pattie and her sister Sarah make an important discovery that survival becomes a certainty.
O livro contém algumas descrições bastante vívidas da vegetação:
One morning when we woke up they were all sick, lying in a heap in a corner of their hutch, with sad cloudy eyes. And by the next day they were all dead. Sarah said they died of homesickness; Father thought they might have caught some kind of virus; most people thought they had been killed by eating the crystalline plants. The chickens were all right; and they had eaten only Earth-grown grain.
Eventualmente, as crianças percebem que apesar dos grãos serem como contas de vidro, eles podem ser esmagados e moídos como farinha:
But Sarah said, "I'm going to try, I'm going to try, I'm going to try!" She stole a handful of the glass beads, and rubbed them between two stones, and they fell easily into a dry white powder that smelled good. She sent Pattie for a ladle of lake water, and mixed a dough, and rolled it out thin, and made a pancake, and cooked it on the fire. Then, when it looked done, she broke it into four pieces, and gave one to Pattie and one to Joe, and bit into one herself, leaving Father's share in the pan.
Oh, it tasted good! We ate it in three bites.
