Boundless

by Jack Campbell

Published 15 June 2021
Admiral John "Black Jack" Geary may have saved the Alliance only to destroy it, in this thrilling and eagerly awaited continuation of the New York Times bestselling series.

Geary believed in the Alliance. Even when he uncovered overwhelming evidence that the highest echelons of the government and fleet command were involved in secret programs and prison camps, he believed it was worth saving. And that his duty was to see that justice was served even though some factions feared that revealing the truth would cause the Alliance to crumble.

But after narrowly surviving two assassination attempts when he brings evidence of the misdeeds to the capital star system, Geary realizes that some have decided the easiest way to make the Alliance's problems go away is to get rid of him. He finds himself ordered to undertake a perilous new mission outside of the reaches of human-occupied space while the Senate clashes over the evidence.

Geary's warships must escort a diplomatic and scientific mission across the dangerous, disintegrating remnants of the Syndicate Worlds empire. But even if he can make it to Midway Star System, the gateway to alien-controlled space, Geary will face former Syndicate officials who have rebelled and regard the Alliance with deep suspicion. And that will be the easy part. . . .

Admiral John “Black Jack” Geary must battle dangers both within and without the Alliance, in this exciting continuation of the New York Times bestselling series.

Geary knows that some political factions in the Alliance were just trying to get rid of him when he was assigned to escort a diplomatic and scientific mission to the far reaches of humanity’s expansion into the galaxy . . . and beyond. But he views his mission as both a duty and an opportunity to make things better wherever he can. And when a crippled Rift Federation ship tumbles out of jump space, Geary leaps into action. But the survivors’ story isn’t completely adding up.
 
As Geary investigates, he soon finds himself fending off spies and assassins while leading the fleet as it fights its way across space controlled by the mysterious and hostile aliens whom humans call enigmas. Challenges arrive at every turn, including an unknown alien species that invites the fleet to visit one of their star systems. With little information to go on, Geary must weigh the benefits of potential new allies against the possibility of a trap. The fate of the fleet—and perhaps even the future of humanity—will depend on him making the right decision.
 
If he can stay alive long enough to do that.

Book 3

Implacable

by Jack Campbell

Published 4 July 2023
Admiral John “Black Jack” Geary fears the greatest threat to humanity may be itself in this gripping continuation of the New York Times bestselling series.

As far from explored space as any human has ever been, Geary and the Alliance fleet are on their own, protecting a diplomatic mission in territory belonging to an alien species with still-unknown motives.

His already complex and dangerous mission is further imperiled by deadly challenges from other human factions seeking to harm or exploit the aliens. When another alien species whose technology is far more advanced than humanity’s arrives, the stakes are raised to the highest possible level.

Only the most serious danger comes from an unexpected source.

Presented with orders to carry out actions he believes not only are mistaken, but would be contrary to the ideals of the Alliance, Geary has to decide whether he must invoke the power that his long-revered name holds--even though this might endanger his entire fleet, tear apart the Alliance, and destroy everything he has fought for.
