The City Of Ember

What I thought of "City Of Ember"
I remember that one of the characters, Doon, said that because of the shortages of the supplies in the city something bad might happen. I seem to forgot what he exactly said in the book.
Have y'll seen the tralier?
I thought it was cool. Now I know that they're trying to get out.
Do y'll remember when Lina went curiously up to the roof of the gathering hall and got scolded for doing so?
I don't think I have been scolded for being curious.
But I do remember the saying "curiosity killed the cat."
