Publisher's Summary

The New York Times best-seller - part of the expanded universe based on the award-winning video game series Halo!

It's 2535. It is the first, desperate days of the Human-Covenant War, and the United Nations Space Command has enacted “the Cole Protocol” to safeguard Earth and its inner colonies from discovery by its merciless alien foe. Many are called upon to rid the galaxy of lingering navigation data that could potentially reveal the location of Earth and ensure the destruction of humanity. Among those tasked with eliminating any trace of such dangerous information is Navy Lieutenant Jacob Keyes - now saddled with a top-secret mission by the Office of Naval Intelligence...one that will take him to a corner of the galaxy where nothing is as it seems.

Out beyond the Outer Colonies lies the planet Hesiod, a gas giant surrounded by a vast asteroid belt. As the Covenant continues to glass the human-occupied planets near Hesiod, many of the survivors, aided by a stronghold of human insurrectionists, are fleeing to the asteroids for refuge. They have transformed the tumbling satellites into a tenuous yet ingenious settlement known as the Rubble - and have come face-to-face with a Covenant settlement of Kig-Yar...yet somehow survived. News of this unlikely treaty has spread to the warring factions. 

Luckily for the UNSC, this uneasy alliance is in the path of the Spartan Gray Team, a three-person renegade squad whose simple task is to wreak havoc from behind enemy lines in any way they see fit. But the Prophets have also sent their very best - an ambitious and ruthless Elite whose quest for nobility and rank is matched only by his brutality....

Good Book, Weak Character Dialogue

The overall story was enjoyable, especially if you are keen to learn more about the lore within the Halo Expanded Universe. But, the book falls short on some noticable fronts, namely the dialogue between characters. There are certainly other Halo books that I would recommend over this.

Great Halo Novel

distracting music

I believe the performance is quite good. I enjoy the story. I liked the addition of sound effects. The nice subtle hum of space craft etc. I found the music to be too sudden and too loud. It felt comical at times and undercut the action instead of supporting it.

overall enjoyed the book.

Worst Halo book so far

Been listening to the halo books in order of release. This is the worst by far. Difficult to get through, extremely boring. Yikes.

Awesome Read

This was an awesome story paired with Mr. Davis' amazing voice acting. The story captivates and provides the reader with vivid ideas of what is happening.

My only critique is that the audio had a few points where it skipped out. this maybe an issue from when I downloaded the audio. luckily, the missing sections we're about a second or two long so it was easy to connect the points that were being conveyed.

Issues in the recording

Sometimes the audio is broken and skips and doesn’t function correctly in this reading. It happens 2-3 times and isn’t a huge deal, but fair to warn of

Don't let negative reviews turn you off.

I honestly don't understand what other people were complaining about with this book. Learning more about Jacob Keyes and Thel Vadame's backgrounds was great. The introduction of Grey team was very interesting as well and added a different flavor to the Spartans as a whole. Just because they don't act like Master Chief, doesn't mean they're not potentially realist portrayals of Spartans. Everyone and every unit is different and has their own personality. I feel like the viewpoint of most of the insurrectionists is well done as well. They're just people trying to do what they see as right with the limited information available to them and the interpretation of that information that their experience has left them with. Finally, why the **** do none of the other reviews mention that this book contains Thel Vadame's backstory as well?? That may have been my favorite part of the book, maybe with the exception of the Spartan throwing a Mongoose ATV around on the battlefield and smashing covenant soldiers with it.

Crappy Arcade Shooter Music

Everything was great, story and reading, BUT I cannot stress enough how much the terrible arcade action music ruined the feel of the book.

I want a refund, poor quality, okay story

Great look into Keyes' background and has some high points but it is far from my favorite. Spartan lore doesn't fit the Halo Culture but its not too far removed. The fight scenes were poor in story and in performance..with weird music... the recording skips out in places.. easily 4 times as other reviews state. Honestly the only redeeming qualities were Keyes and some cool ambient scene noise for the pelican scenes

Obnoxious music

The loud, obnoxious, and completely unnecessary music completely ruined this book. Wish I had never wasted my time, money, or credit.

The worst of the halo books

Absolutely garbage. couldnt even finish the book because the annoying audio in the background. The producer added fake ship noises in the background that never change in tone whenever the story takes place on a ship. they add random music which is way louder than the spoken story narration which forces you to constantly have to change the volume up and down. 33 books into audible and this is the worst by far.

some back story

no cheif, and that's not bad. Jacob Keys is primarily focus. some spartans, there is also a real pov
the music was a little too intense at times, but not a bad idea. I would have liked a show, radio, game, editor to have reviewed the eq.
