Publisher's Summary

The first novel in the Forerunner Saga trilogy by science-fiction legend Greg Bear - set in the Halo universe and based on the New York Times best-selling video game series!

One hundred thousand years ago, the galaxy was populated by a great variety of beings. But one species - eons beyond all others in both technology and knowledge - achieved dominance.

They ruled in peace but met opposition with quick and brutal effectiveness. They were the Forerunners - the keepers of the Mantle of Responsibility, the next stage of life in the Universe’s Living Time.

And then they vanished.

This is their story.

Interesting take to the unwritten history.

I really enjoyed the book so many questions I've always wanted answered. The book is well written and keeps you engaged.

Best Halo book I've "read"!

I love Halo and have since Halo 2, but I had never read any of the books. When I heard a series was releasing about the fall of the forerunners, I had actually listened to this book right after it came out, marking it as my first. this book is phenomenally thought out, presenting a whole new living universe never truly explored before. I recommend this to all who love Halo, though it is hard to understand it's true scope without at least playing the first 3 games. Get this book, and its sequels; Primordium and Silentium. You won't be disappointed!

Hold on, it gets better.

The beginning or first half I struggled with, there were no answers and continuously produced mysteries that made no sense. Suddenly a chapter began and I couldn’t get enough, answers poured in and deep lore was like rapid fire. In the end I very much enjoyed the novel and recommend it to any Halo fan who wants to know more about the Forerunners, Promethians, Flood, or in general some backstory to the 4th game.

look, it... well it gets better.

This is a slow listen. But it fills out some information on "Why's and How's" of the Forerunners. The performance of the narrator is good, and the story stays mysterious till the end. Maybe?

Halo Ethnography

My love of Halo franchise carried me through this. But my distaste of ethnographies... 3/5

Halo 4 is much better because of this trilogy

This book was a surprise to me. it showed me that there was far more to the Halo 4 Story than the game showed. This trilogy actually made me appreciate Halo 4 far more than the base game did.

Well done, as expected.

The story was better than you would expect if you are looking for a deeper lore in Halo. The narrator was perfect. If you are a Halo fan, give it a try. If you are new to the series, this book will make you a fan.

A nice start chronologically speaking

Well read and voice acted but story jumps at times into odd areas which add nothing to the lore or story. Overall if you like Halo you will enjoy this.

Lore Porn Mk. 2

I read a review of Halo: Glasslands a little while back that simply said “lore porn” and I agreed with that statement though a lot more could be said about that series of novels. But I would state that this trilogy (especially that of Cryptum) is also “lore porn”. If you’re a fan of the Halo series and you want to learn about the mysterious Forerunners then this trilogy is for you. But it’s also a fantastic listen for anyone from outside of the Halo fandom. It’s definitely worth your time if you like exciting and bizarre science fiction.

FAN Flipping Tastic!!

Recommend by 3 great friends and family to dive into this series I finally took the plunge with this audiobook and got damn, what an epic journey and starting point for the trilogy, having only read Contact harvest and Cole protocol as paper backs this was my first experience with listening to an audiobook and by golly was it a joy. Many thanks to the reader and to my man Greg for crafting and sharing this wonderful experience I can’t wait to jump into book two!

A good addition to the lore.

Excellent story and narration, though a little slow at times, makes it up with action fueled narrative and personality.
