the City of Ember: Chapter 17

In chapter 17, Away, Doon is waiting for Lina at the pipeworks. At the last second, she arrives with Poppy in her arms. They climbed down to the river room, where they found *paddles in the boat, but they couldn't figure out how ti use them, so they put them on the floor. Then, they finished setting it up, all hopped in, and set off on our journey.

*They don't know what it is.

QUESTIONS: Do you think they'll survive? How did Lina get Poppy? What do you think the place they're going's like?
