As the book went on, the book started to make more and more sense. The main characters were mentioned, and they became part of the action too. Well, I don't know if they were part of the action actually, but that's just because there wasn't any. The book got more interesting as you got farther into it. The characters started to do more, and the plot became hotly anticipated.
If you have read the Ember books, you might of noticed this too, but to me it stood out. All books in the Ember series have titles that are The Blank of Blank. They are all called The Something of Something. I notice this as similarities, and I think it might be a style of the authors writing.
The People of Sparks is a great book so far, and if you're looking for a good book to read, I sure hope you choose this one!
