The People of Sparks

I read The People Of Sparks, by Jeanne DuPrau. It is science fiction (post-apocalyptic ).It's in the way future, but it seems like the past. (You'll know what I mean when you read the book. ) It is the second Book Of Ember (sequel to The City Of Ember). In The City Of Ember, Lina Mayfleet and Doon Harrow find their way out of their underground city, which they have lived in for many years. They never even know that it was underground. They wander for days out side, exhausted and hungry.
The People of Sparks continues the story about them. The Emberites finally come to a little village called Sparks. At first, the people of Sparks are very generous and give them lots of food and stuff. Then, they start hating each other, being mean, and hitting each other, because they think the Sparks people are dumb and don't know what the seasons, bread, and other common things are. They treat them badly. People get angrier and angrier, and then there is war. They have to find out some way to stop it, or they'll die. . . .

Connections--We learned about SF in the classroom, and post-apocalyptic is a type of science fiction. Also, this book reminds me that maybe someday there will be a war and only a few people survive.
Reactions-- This book made me want to read on and on, because it was really exciting.
It was also sad in some parts.
Opinions-- I really like how this book makes you think. Also, it's what really could happen in the future. Maybe in the future, the whole world would be almost destroyed, and there would be people that survived and had to start from scratch again, with no computers, movies, TVs and things like that. Also, this is a pretty good book.
Predictions-- I think that in the next books, it will tell how the Emberites rebuild the destroyed city.
Questions:-- I wonder why the Sparks people were so mean to the Emberites? In the beginning they were very nice.
Visualizations-- In my head, I could see the destroyed city, with the roofs stripped off buildings, rubble everywhere, dirt, stuff like that. I could also see how it looked after it was rebuilt.

Also, do you like the font in the summary? (It's Kristen ITC and Comic Sans MS)
