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

Slow start but awesome book

I was a little worried at first because it started off rather slow, but then it just kicked into overdrive & I couldn’t stop listening. Hell of a book.

a needed look at the backstory of the forerunners

if you've ever wondered about the forerunners, the flood, the precursors, or mendicant bias, than this is what you need to listen to.

Leaves more questions than answers

a solid attempt to backfill the ancient lore of the Halo-verse. Big shoes to fill, and it's a good attempt. Not terribly exciting.

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.

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.
