Audio Book vs Book

Has anyone else listened to the audio book of The Hunger Games? I read the first book and thought that Katniss was a tough, awesome, fearless girl. Yet, in the audio book, the narrator reads her as being hesitant and unsure of herself. Did anyone else think this? Did I read more toughness into Katniss than I should have? I think that's why the book is always better, because you can let your imagination decide the character's looks, tone, and other details with a little help from the author. We all read it a little differently and that's what makes a discussion about the characters so fun. I'm curious to hear what other people thought about this.

i've never listened to an audio book. i would rather sit down with a book, than put in my earphones. haha
i definately thought Katniss was really tough. she can hold her own!

who was the narrator?
