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.

A Good starting point for this trilogy!

I personally really liked the book. The characters were all different and likeable. The voice artist had a wide range of voices, where only a couple times I didn't know who was speaking until the book told me. The book gives good explanation of certain aspects of Forerunner culture that seem other worldly today (like the Domain for example). The explanation of the first location (the island) however is really confusing. I may of missed some key details but I could never grasp what the true look of the island was in my head. it was pretty frustrating but at the end of the day isn't a breaking point at all. My only gripe about this book, is that it's fairly slow and nothing really happens in it until the last 8 or so chapters. The most interesting stuff throughout the whole book is the main character going through memories of past ancestors. Even though I think this is a slow build up book, it clearly sets up the next 2 in the trilogy which I'm confident will be more action packed, due to all the tedious explaining of forerunner culture thouroghly explained in Cryptum. I love Halo and can't wait to see where the next book takes me.

Required reading for Halo fans

Absolutely stellar book, can’t say enough good things about it. Holter Graham does an incredibly job acting out the story, too, enough that I’d recommend the audiobook even if you’ve read Cryptum before.

little drawn out, but has good lore.

This book does contain interesting lore about the halo universe, but I did find it to be far slower and less exciting than the other halo books I've read. there were numerous instances or events in this book that took several chapters to describe, I was hoping for more exciting events, battles, or pieces of lore that would have me struggling to put the phone down and go to bed, which was something I had to do with the previous books, halo evolutions specifically. But overall, though I believe it to be drawn out, it's a good book to read if you're as thirsty for halo lore as I happen to be.

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

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.

Forerunner knowledge

This is a start to a very complicated forerunner trilogy. decent start, confusing at times but the author talking at the end reviewing his intentions was very nice.
