The Green Book, by Jill Paton Walsh, 1982

Father says they may only bring one book each on the ship that will carry them from Earth, on the verge of destruction, to the nearest habitable planet. Joe brings Robinson Crusoe, and Sarah a pony story, but Pattie brings The Green Book, which is blank. Their new planet, which Pattie names Shine, has air and water and sparkling vegetation as if made of glass -- but can it sustain them? A lean, graceful text, simple yet compelling, with not a word out of place. Its unusual point of view stance is ultimately rewarded. Strongly recommended.
