What it feels like

Reading this book feels like unearthing a monumental, forgotten history. It trades the run-and-gun action of its source material for a steady, awe-inspiring exploration of deep time and cosmic hubris. The atmosphere is vast and ominous, steeped in the melancholy of an impossibly advanced civilization teetering on the edge of its own making. The prose is dense with conceptual sci-fi and mythic grandeur, demanding a reader who loves to sink into complex worldbuilding and alien societal structures. As the narrative unfolds, the initial spark of youthful rebellion gives way to a heavy, creeping dread. It will deeply satisfy fans of grand-scale space opera who want to wander through the ruins of ancient, god-like empires and ponder the devastating weight of absolute power.

About the book

100,000 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, the next stage of life in the Universe’s Living Time.

And then they vanished.

This is their story.

Bornstellar Makes Eternal Lasting is a young rebellious Forerunner. He is a Manipular, untried--yet to become part of the adult Forerunner society, where vast knowledge and duty waits. He comes from a family of Builders, the Forerunners’ highest and most politically powerful rate. It is the Builders who create the grand technology that facilitates Forerunner dominance over the known universe. It is the Builders who believe they must shoulder the greatest burden of the Mantle--as shepherds and guardians of all life.

Bornstellar is marked to become a great Builder just like his father.

But this Manipular has other plans.

He is obsessed with lost treasures of the past. His reckless passion to seek out the marvelous artifacts left behind by the Precursors--long-vanished superbeings of unknowable power and intent---forces his father’s hand.

Bornstellar is sent to live among the Miners, where he must come to terms with where his duty truly lies.

But powerful forces are at play. Forerunner society is at a major crux. Past threats are once again proving relentless. Dire solutions--machines and strategies never before contemplated--are being called up, and fissures in Forerunner power are leading to chaos.

On a Lifeworker’s experimental planet, Bornstellar’s rebellious course crosses the paths of two humans, and the long lifeline of a great military leader, forever changing Bornstellar’s destiny...and the fate of the entire galaxy.

This is a tale of life, death, intergalactic horror, exile, and maturity. It is a story of overwhelming change--and of human origins. For the Mantle may not lie upon the shoulders of Forerunners forever.
