Publisher's Summary

In the last years of the Forerunner empire, chaos rules. The Flood - a horrifying shape-changing parasite - has arrived in force, aided by unexpected allies. Internal strife within the ecumene has desperately weakened Forerunner defenses.
Too little, too late, the legal rate of Juridicals is only now investigating possible crimes by the Master Builder and others. Evidence-gathering agents known collectively as Catalog have been dispatched to collect testimony from the Librarian and both Didacts: the Ur-Didact, treacherously abandoned in a Flood-infested system, and the Bornstellar Didact, who accompanies the Librarian as she preserves specimens against the dire possibility of Halo extermination.
Facing the imminent collapse of their civilization, the Librarian and the Ur-Didact reveal what they know about the relationship between the long-vanished Precursors and the Flood. The Precursors created many technological species, including humanity and the Forerunners. But the roots of the Flood may be found in an act of enormous barbarity, carried out beyond our galaxy 10 million years before.... Because of that barbarism, a greater evil looms. Only the Ur-Didact and the Librarian - husband and wife pushed into desperate conflict - hold the keys to a solution. Facing the consequences of a mythic tragedy, one of them must now commit the greatest atrocity of all time - to prevent an insane evil from dominating the entire universe.

The forerunner story has come full circle.

This a great prequel story to the Halo saga. Questions about how it all started and the ultimate purpose of everything is contained in this book.
This is a must read for all Halo fans and it sets the stage for all the games. I am now looking forward to what happens next in Halo 5.

An intriguing conclusion to the Forerunner saga

The book is filled with incredible lore, and the performance - though a little monotonous at the very beginning - was overall very good.

Not the best

Story is ok but the performance is a slog to get through. I think this is because of the tone of the characters being quite deadpan.

Pretty good for Halo fans

A good finale but perhaps not best suited to audio book, was a bit confusing at times and jumped around a lot. His voice was pleasant but wasn't really distinct enough between characters so that also added to the confusion. Tied up some loose ends so worth a read if you're a halo fan
