In the concluding installment of this genre-defying, heart-pounding space opera trilogy, Essa Hansen, a fresh and exciting voice, takes readers on an unforgettable adventure that will captivate fans of The Expanse and A Long Way to a Small Angry Planet.

After a decade of fleeing with his remarkable starship, Caiden has finally been reunited with his sister Leta. However, the multiverse remains perilous. Abriss, Threi's sister, remains the most formidable being in existence, driven by her desire to collapse the diverse and interconnected constellation of universes into one, growing more powerful with each universe she destroys.

As Abriss's strength increases, her sanity teeters under the weight of the universe's whispers. Caiden faces a critical decision: whether to unlock the ancient Graven abilities latent in his genetics and save the multiverse, risking losing himself to the whispers, just as Abriss has. With the fate of all worlds in their hands, Caiden and his makeshift family must confront their deepest fears and embrace their destiny.
