From what point of view is the story told?
Cinder, by Marissa Meyer, is written from the third person perspective. The opening paragraphs give a lot of opportunity to figure out the narrative perspective. The following line is a good example.
She slumped back with a relieved groan.
"She" is a third person pronoun. If the story was written in first person, the sentence would have read "I slumped back with a relieved groan." If the story were written in second person, the sentence would have read "You slumped back with a relieved groan."
A more specific explanation of the narrative perspective is that the story is written in the third person omniscient point of view. That means the narrator knows everything. He knows the thoughts and opinions of the main character as well as the thoughts and opinions of minor characters and bad guys.
