In this scene The mayor visits Lina and Doons class to give the students their permanent jobs. Lina draws the job of Pipe works and Doon draws the job of messenger they trade jobs because Doon wants to try to fix the generator. I chose to include this scene because If Doon and Lina had different jobs they wouldn't have found the door in the roped off tunnle
In this part of the novel Lena comes home to find poppy eating paper that turns out to be the instructions Lena places the paper locked together and discovers that the paper is talking about a door in the pipeworks. This scene is important to the story because if Lina didn't find the paper Lina and Doon wouldn't have known to look for the door in the pipeworks.
In this scene Doon shows Lina the door he has found in the pipeworks. While they are they see a strange but familiar man who unlocks the door. I consider this to be an important event because If they didn't find the door they might not be able to escape Ember.
I think that at the end of the novel… Lina and Doon will find more pieces to the instructions that will tell them where they key to the locked door is they will open the door and explain it Amber by following the light to the Earth's surface !.
