Just got the book, read through it.. Fantastic read. The graphics were incredibly detailed, and i'm glad that they didnt have any of the stories in the novel based on the Master Chief.. All of the stories more or less revolved around what else was going on in other places while the chief was doing his thing.
I like the fact that they expanded the thoughts of the readers so we now think, 'Holy crap, the halo universe is huge and they can write thousands of different stories based on it'.. Obviously the writers/artists were very familiar with the game/storyline as the fluidity of each story(there are 4 different stories in the book) were amazingly fitting.
I highly suggest picking this book up, makes for a fantastic read and a good keepsake!
