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.

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

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.

Great story, but quite a few audio issues

The Cole Protocol is another thrilling story taking place in the Halo universe. Great to read about several new locations such as the Rubble, Hesiod, and Metissete. Jacob Keyes continues to be a great character, and hearing more of his experiences makes him even sound even more great. The significant focus on Thel Vadamee (the Elite who you may know as the Arbiter from the games) and his Covenant fleet was one of my favorite parts of the storyline. All settings and standoffs are given vivid descriptions, making you feel as if you really are on a spacecraft, asteroid belt, or a frozen methane-filled moon, while dodging projectiles or plasma blasts. Definitely recommend this book for those who want to learn about Human-Covenant clashes outside of the main storyline of the games. As great as this book is, the audio for this presentation has several issues. Multiple times, the recording got scrambled or skipped around, omitting or blurring several words in a sentence. I thought it was due to something wrong with my headphones, but the issue was consistently occurring after rewinding to the same spot. Other comments have indicated the same thing. While most of the pronunciation of words is good, there are occasional slip ups, such as pronouncing the planet "Sanghelian" (it is really "Sanghelios"). I thought the frequent use of music and background sound effects was interesting, and made several parts more intense and exciting, but a lot of other times the sounds did not feel like they fit with the scene. In short, I highly recommend The Cole Protocol, but it may be better to buy a hard or electronic copy, or somewhere outside Audible, at least until or unless the audio issues are addressed.

Good story, but issues with the audio.

I enjoyed the story and recommend to those that like futuristic military science fiction. Low performance rating due to tech issues with the audio. Several times the audio jumbled in the same areas, even after removing from device and re-downloading the file.

Just as good as I remember it!

I read this book years ago when it first came out. Getting to listen to this story was an absolutely phenomenal experience. The Cole Protocol is by far my favorite book from the franchise. It has a little bit of everything in it. We get to see the inner machinations of the political turmoil in both the UNSC and the Covenant. We get some great action sequences throughout. Plus, we get to delve into some of our favorite characters lore such as Jacob Keyes and Thel Vadam’ee (aka The Arbiter). It’s such a fantastic story and it will always hold a special place in my heart. Hats off to you Tobias S. Buckell.

Too much noise

Far too much music and “flavor noise.” Also, random portions are missing in small segments

Story of Keys impressive feats!

This story is sort of a standalone from all the other books. Featuring Keys as an impressive thinker from previous books. Sadly the audiobook had some audio issues but still an interesting book following the importance and plot of the Cole Protocol.
