The Halo Grapic Novel is four comics brought together into one book. I know it wasn't very professional of me, but I didn't even read one of them because I hated the art so much. But here are the other three.
The first comic is The Last Voyage of The Infinite Succor. It follows SpecOps Commander Rtas 'Vadumee, and his team while investigating a loss of communication with an agricultural ship. It also follows MCPON John-117 while in the swamps of Installation-04's Flood Containment Facility. I don't want to give any spoilers, because it's such a good story, so I'm not going to say any more on it. The art is a little gritty for my taste, but that might be what the author was trying to portray.
The second story is a relatively short comic, Armor Testing. It just shows a testing session of the new MJOLNIR Mark-VI Powered Assault Armor. The testing takes place on Earth, and the one wearing the new armor is Spartan-II Maria-062. The comic has good, clean art, and is actually a quite interesting look at the Mk VI armor.
The third story, Breaking Quarantine, is about Sgt. Johnson's escape from the Flood Containment Facility. There are no words, I think because the "author" is Japanese, and doesn't speak English.* It's a good story overall, and one that Halo fans wondered about, until this came out.
The fourth and final story is Second Sunrise Over New Mombassa. As I said at the beginning of this review, I did not read this one. I tried to, I really wanted to. But the art was just too hard to get past. You can see the artwork at the bottom of the review.
All in all, even though I didnt like the fourth story, the Graphic Novel is worth reading for any Halo fan, although I would never buy it. 3 out of 5, 7 out of 10.
