Treetop Treasures - Making a Prediction

I have just been learning to make a justified prediction about a text bused on the cover and the blurb. We read a novel caled treetop treasures. My prediction wasn't accurate because the chapters were hard to predict. Some think that surprised me was that the chapters were realy short. My next step is to look carefully at the cover and the blurb to help me think about what the story will be about.
