Let me preface this by saying that if you plan on seeing the movie and haven't read the book yet, I highly suggest you read the book first. They change quite a bit in the movie, and you don't want the images from the movie spoiling what your imagination could produce."The Hobbit", first and foremost, is a children's novel. Tolkien did not write the book like he did "The Lord of the Rings", so it doesn't read like it bigger brothers do. It is fairly more complex than what you would imagine a children's book to be, but it is written in a more simple fashion compared adult novels. I don't think this takes away any enjoyment from the reading, though.
This novel is the definition of epic adventure. It has a long journey, wild surprises, narrow escapes, and to top it off a huge fire-breathing dragon. There are gruesome creatures, big battles, people get slaughtered; doesn't sound like the average children's novel, does it?
This book is a quick, fun read. It is a classic, and if you are a fan of fantasy or "The Lord of the Rings" trilogy, it is definitely worth a read.
