Query: Great books

I am a big fan of the halo video games, and I wanted to know what happened before the first game and in between the games. These books are great novels. I read them all in less than a week. I just couldn't put them down. I was going to buy them from bungie and the were going to be $29 with shipping so I looked around and I found them here for much cheaper. Great books, great price.
