The third book in the New York Times bestselling Expanse series, Abaddon's Gate opens the door to the ruins of an alien gate network--and the crew of the Rocinante may hold the key to unlocking its secrets. Now a Prime Original series. For generations, the solar system--Mars, the Moon, the Asteroid Belt--was humanity's great frontier. Until now. The alien artifact working through its program under the clouds of Venus has appeared in Uranus's orbit, where it has built a massive gate that leads to a starless dark. Jim Holden and the crew of the Rocinante are part of a vast flotilla of scientific and military ships going out to examine the artifact. But behind the scenes, a complex plot is unfolding, with the destruction of Holden at its core. As the emissaries of the human race try to find whether the gate is an opportunity or a threat, the greatest danger is the one they brought with them. Abaddon's Gate is a breakneck science fiction adventure following the critically acclaimed Caliban's War. "Interplanetary adventure the way it ought to be written." --George R. R.
