Query: My least favorite book of the series.

And for good reason. The book doesn't really delve into any backstory or characters. It's basically a walkthrough of the game. Some parts are really good, but then go into pages upon pages of Master Chief mowing down Covenant and Flood. I just couldn't give it more than two stars because there were just too many pages of mindless killing of Covenant. We understand the book is based off of a video game, but it doesn't need to be an exact walkthrough of the game. I'd like to see future authors branch out a little more and really create more of a Halo Universe. Definitely a skipable book in the Halo series.
