Captain MacKenzie Calhoun has faced incredible odds before, but nothing he has ever experienced could prepare him for the simultaneous threats from two of the most destructive forces he’s ever encountered. The first is the D’myurj—a mysterious and powerful alien race bent on either the complete domination of humanity or its destruction... a potentially massive risk to the very foundations of Starfleet, one that goes so deep it’s impossible to determine whom to trust. The second is even more alarming: Morgan Primus, once a living creature with a soul and a conscience, now an incredibly sophisticated computer simulation taking up residence within the very core of the U.S.S. Excalibur... and quickly becoming a growing menace for the Federation. MacKenzie Calhoun is playing a dangerous game as he attempts to outwit and outmaneuver these new enemies, with the fate of the Excalibur crew members and potentially the lives of billions at stake...

The first installment in a brand-new three-part digital-first Star Trek: New Frontier e-novel from New York Times bestselling author Peter David! Captain Mackenzie Calhoun and the crew of the U.S.S. Excalibur are back, picking up three months after the stunning events depicted in New Frontier: Blind Man’s Bluff. Calhoun's search of Xenex has failed to find any survivors, and now he is bound and determined to track down the race that killed them—the D'myurj and their associates, the Brethren—and exact vengeance upon them. His search will take the Excalibur crew into a pocket universe, where he discovers not only the homeworld of the D’myurj, but another race that shares Calhoun's determination to obliterate his opponents. But is this new race truly an ally…or an even greater threat?

Nothing could have prepared Captain Calhoun for simultaneous threats from the D'myurj, bent on the domination or destruction of humanity, and Morgan Primus, a sophisticated computer simulation taking up residence within the very core of the U.S.S. Excalibur.

Klingons and Cardassians rule the Alpha Quadrant in an uneasy alliance that hides a viper's nest of backstabbing plots and counterplots. Annika Hansen has become a trained operative for the Obsidian Order. Her latest target: Kira Nerys, the duplicitous Intendant of Bajor, whose ruthless ambition has brought her to a position of power second only to the Regent himself, the fierce Klingon warrior known as Worf.

Captain Mackenzie Calhoun has often been accused of playing God, but he has never faced off against real gods—until now. As Captain Kirk did before him, Calhoun has encountered beings of unnatural power and abilities verging on godhood, and who claim to be the very individuals who inspired the Greek, Roman, Norse, and, other pantheons from Earth culture. These beings say that all they want is our worship, and in return for it will provide us with a peaceful galaxy-wide paradise of perfect health and endless pleasure. When the Federation, in the person of Captain Calhoun and the crew of the U.S.S. Excalibur, refused their offer, the resulting battle left Morgan Primus dead and Lieutenant Mark McHenry, whose own powers over time and space had proved to be substantial, in a limbo beyond death. Now, with a wounded ship and an injured crew, Captain Calhoun, along with Captain Shelby and the crew of the Trident, must face these god-like beings once again, with the fate of galactic civilization at stake.

Seven years have passed since a catastrophic explosion on the Klingon moon Praxis touched off a chain of events that would result in the assassination of the reformist High Chancellor Gorkon, and the eventual creation of the historicKhitomer Accords. Now, as part of the ongoing efforts to undo the disastrous fallout from the destruction of Praxis and with the help of aid supplies from the United Federation of Planets, reconstruction is in progress, and after years of slow going hindered by political pressures and old prejudices, headway is at last being made. But the peace process begun by theKhitomer Accords is still fragile just as the deadly plans of what is believed to be a hard-line Klingon isolationist group violently come to fruition. Yet the group thought responsible for the deadly attack has been dormant for decades, and its known modus operandi doesn’t match up to the manner of the strike. And further investigation leads to an unexpected revelation connected to the Gorkon conspiracy of 2293, and in particular one disgraced and very familiar Starfleet lieutenant….
