The Station is under siege by the Grey once more, as the crew of the Helena struggle to catch Siroc before he arrives at the Dyson Sphere. While the battle rages outside, Shelby and Lefler are leading a skeleton crew of 93 in a desperate ploy to restore Excelsior and rejoin the fight to protect the station's civilians.
With time completely gone, all hope lies in Knapp, Martinez, Dao, Aster and McFarland being able to figure out the Hybrid; but things are far more different - and deadly - than they seem.
When sudden and brutal attacks by the Tholians and Breen begin to target both Starfleet and civilian craft alike, Captain Shelby must begin to battle for the hearts and minds of the Federation's closest allies. Meanwhile, Admiral Cole is confronted with overwhelming odds and an increasingly restless civilian crew in a desperate battle to survive.
Shelby's recovered the hearts and minds of Starfleet's allies against Siroc and the Tholians - but it may be too late. With the return of an old friend and the loss of new ones under tragic circumstances, Excelsior is in a desperate race to get back to her home station, as the entire patch has suddenly gone deathly silent.
If things weren't bad enough, it has come down to the wire for Naros' race to beat Siroc to the Dyson Sphere and stop him from carrying out his mission. With Ro's capture, Siroc's entire checklist for his final plan is complete, and using the stolen memories from Counselor Elbrey, all that's left is getting there first.
Old enemies, old friends, and old ideas are shaken up as Siroc's plans shift ever closer to their devestating conclusion; things are collapsing right under the feet of the Allies as he draws nearer to his victory.
Meanwhile, Shelby has to face up to the toughest challenge of her career with less help than she's ever had, Dao must face his past if he has any hope of going into the future, and the prisoners must make their stand if they hope to survive the seemingly mindless brutality of Siroc and his henchmen.
Disaster has struck for the 12th Fleet - right at the worst time it could happen. Admiral Cole and the Independence are gone, but their closest friends have no time to grieve. Now that Siroc has someone who knows the location of the Dyson Sphere, it looks like it's only a matter of time before everything is lost.
But that's not the only thing to worry about. The Romulans and Klingons have become restless and are beginning to talk of withdrawing from the effort against Siroc if Starfleet remains as leader of the campaign. With the walls closing in on all sides, Shelby must bear increasing pressure to win back the hearts and minds of Starfleet's allies and contend with her shrinking pool of friends and family.
