AN OLD ENEMY RETURNS
In the thousand-sun network of humanity's expansion, new colony worlds are struggling to find their way. Every new planet lives on a knife edge between collapse and wonder, and the crew of the aging gunship Rocinante have their hands more than full keeping the fragile peace.
In the vast space between Earth and Jupiter, the inner planets and belt have formed a tentative and uncertain alliance still haunted by a history of wars and prejudices. On the lost colony world of Laconia, a hidden enemy has a new vision for all of humanity and the power to enforce it.
New technologies clash with old as the history of human conflict returns to its ancient patterns of war and subjugation. But human nature is not the only enemy, and the forces being unleashed have their own price. A price that will change the shape of humanity -- and of the Rocinante -- unexpectedly and forever. [4]

Thirteen hundred gates have opened to solar systems around the galaxy. But as humanity builds its interstellar empire in the alien ruins, the mysteries and threats grow deeper.
In the dead systems where gates lead to stranger things than alien planets, Elvi Okoye begins a desperate search to discover the nature of a genocide that happened before the first human beings existed, and to find weapons to fight a war against forces at the edge of the imaginable. But the price of that knowledge may be higher than she can pay.
At the heart of the empire, Teresa Duarte prepares to take on the burden of her father's godlike ambition. The sociopathic scientist Paolo Cortázar and the Mephistophelian prisoner James Holden are only two of the dangers in a palace thick with intrigue, but Teresa has a mind of her own and secrets even her father the emperor doesn't guess.
And throughout the wide human empire, the scattered crew of the Rocinante fights a brave rear-guard action against Duarte's authoritarian regime. Memory of the old order falls away, and a future under Laconia's eternal rule -- and with it, a battle that humanity can only lose - seems more and more certain. Because against the terrors that lie between worlds, courage and ambition will not be enough...

The biggest SF series of the decade comes to an incredible conclusion in the ninth and final novel in James S.A. Corey’s Hugo-award winning Expanse series – now a Prime Original series.
