Description

Caiden has finally been reunited with his companion Leta after ten years on the run with his unique starship and managed to convince his longtime enemy—Threi—to join his side. But the multiverse isn’t safe yet. Threi’s sister Abriss is still the most powerful being in existence. And she still wants to collapse their beautiful, diverse, constellation of universes down to one, growing more powerful and more ruthless with each unique world she destroys.

As Abriss’s strength grows, her sanity wanes under the burden of the universe’s whispers. And Caiden must weigh his final sacrifice against a new risk: if he finally unlocks the ancient Graven abilities lying dormant in his genetics and saves the multiverse, he might lose himself to the whispers just as Abriss has. For the last time, Caiden and his makeshift family must carry the fate of all the worlds in their hands.

Reviews

Multiple points of view allow readers to delve into their beliefs and traumas, creating a character-driven story across space and time. The final book of “The Graven” trilogy, after Azura Ghost, digs deep into the multiverse, along with themes of genocide, utopian idealism, and autonomy.

Library Journal

Kristi Chadwick

Parallel universes pop like champagne bubbles in the fizzy and frenetic final space opera of Hansen’s Graven series. … Not for the uninitiated, this outing takes a cosmic perspective, rapidly oscillating between distant pasts and wild futures with Caiden and his friends often caught in the turbulent temporal shifts. Luckily, a deeply human spark of loyalty among the fighters keeps the chill of the multiverse from freezing out its readers. This proves a worthy finale.

Publishers Weekly

Hansen doesn't just build worlds, she engineers fresh universes, weaves depth into incredibly charismatic characters, and balances kick-ass combat scenes with galactic stakes. Ethera Grave pulls it all together and absolutely nails the landing. It'll tear your heart up in all the best ways.

Shelly Campbell

author of Under The Lesser Moon

Some writers have a big finish in which worlds collide, but for Essa Hansen, nothing short of a final confrontation in which universes collide will be fitting for closing the tale of Caiden, Leta, Threi and Abriss. It's just as mind-bending as you'd think when the very fabric of existence unravels in this last battle of powerful forces and the wills behind them.

Wayne Santos

author of The Chimera Code

Essa Hansen's spectacular imagination is on full display in her third novel: ethereal ships ride bursting bubble universes, all-powerful siblings battle for the soul of the universe, and ancient alien genetics fuel the machines of war. Her work is catnip for dedicated readers of thought-provoking science fiction.
