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.
