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....

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

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

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.

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.

Great story; presentation needs work.

I liked the occasional background music, but it was overpowering at times. Sometimes, I struggled to differentiate between the different characters and the narrator.

Fantastic listen!

First, the narration was on point! He really made it easy for me to visualize each scene as it was happening. 10/10

The story itself is just top teir, it referenced back to so many other things that were mentioned throughout the Halo Universe as I've read into it so far! Can't wait to venture into the next story.

Unnecessary music was added in the production. Totally distracts from what is a decent story.

Good story with some occasional audio bugs.

The story and narration were just fine but there were a couple of bugs in the audio that caused some very slight but still noticeable skips and loops.

Great book

Great book and most importantly the Narator is good, but there are three occasions where there is a stutter and it appears to skip by 5-10 seconds. You don't appear to miss much.

Environmental background sound effects are good but the dramatic background music got a tad annoying. Thankfully the Narator worked with it well so it was still easy to listen to.

Audio skips/bugs

The narrator and music are great for this story. The story itself is awesome. I love hearing more of keyes background. Only downside is the several audio skips, which can throw you off but I believe they’re only 10-15 secs long.

Good Story

I’m making my way though the Halo books and like the 5 before this one had me hooked. It’s a good story and keeps you wondering what’s coming next but I have two issues with this book, the first is the number of chapters is really stupid, it’s a joke. And the second is the time line, I struggled to work out when this was happening in the Halo story lines.

Must reads for fans of Halo

The whole run of Halo books are must reads if you are a fan of the games.

The deeper look into the story behind the games is incredible, especially as the books aren't centred around Master Chief John 117, you not only get stories from other Spartans, but other UNSC characters and from The Covenant.

Good book, good narrator, iffy recording.

Story is good and I enjoyed the voice acting but there are certain parts of the recording where the narrator will glitch for a moment then jump forward a few seconds, not too far that you can’t follow it but it can be annoying.

music was a miss

didn't like the music in this. it didn't need it. and if they really wanted the music, focus more on adding it correctly and more often
