Blast Off! Let's Explore Neptune by Helen David Orme
"The castle, and all it represents, will always be with us. Once it was born, once the stone was made living, the repository of power made real, the idea could never be unmade. Even if all the castles of all the world were destroyed, in the minds of men they would be built anew; the wizard called imagination would raise high walls and towers out of ruins." - David Day
