New book Intro

Ok first of I have to be honest with you all I have already watched the movie for the hunger game and my intro will have a lot of ruining facts. Catching Fire's setting is a bit confusing, but the main settings are the districts, where Katniss & Petta are visiting to apologize to the family of the kids that died in the Hunger Games. Catching Fire is written by Suzanne Marie Collins is an American television writer and novelist, best known as the author of The New York Times bestselling series The Underhand Chronicles and The Hunger Games trilogy. She has won the Dorothy Canfield Fisher Children's Book Award. I chose this book because I love to read science fiction novels I like the way author use their imagination to make something so beautiful such as Catching Fire and The Hunger Game, also a newer book like Mocking Jay. Some question I have before I start to read this book are, Is the book going to be the same as the movie? and Why did snow change the map of the Game???
