I my opinion New Moon was BY FAR the worst book! But it was worth reading in order to get to Eclipse and Breaking Dawn :)
But whatever you do just remember that Edward is Better than Jacob no matter what the actors look like lol :) I'm just kidding! But seriously the CHARACTER of Edward is sooooo much better than Jacobs character :)
In my opinion, New Moon was not the best book in the Twilight Saga, but it wasn't the worst either. I didn't think it was the same without Edward, but I also liked that the reader gets to see more of Jacob and his thoughts on the whole vampire thing.
I have a word of advice since you just started reading the Twilight Saga. I started reading it last year, and a lot of my friends tried to encourage me not to read it because they said it was really bad. I think you should read all of them, and then you can say if they're bad or not. Don't stop reading them just because a lot of people were dissatisfied with Stephanie Meyer's work, or they thought the movies were bad (some of them didn't even read the books! so they should just shut up). Personally, I loved the books, and I hope you will too :) .
