In the distant future and on a distant planet, brother-warriors Galen and Chor are sent to a nearby moon to rescue a woman whose mental abilities, still untrained and untried, must stand in the way of an advancing enemy. But the simple assignment turns into a battle for their own survival and their freedom when the truths they discover force them to oppose the will of their ruthless and cruel leader. Reviled as demons by the people living on the moon and pursued by mysterious gods living on another, the brothers will have to decide between the destruction of one civilization and the future of their own world. One woman can help them escape the bonds that enslave them, but what sacrifice are they willing to make to escape the violent passion that threatens to destroy them?

Dropping out of sub-space into the wrong galactic sector, Sethran Kada wakes up with a headache and an extraordinary alien aboard his ship. She implores him to help stop the abductions of her people, a newly evolved species emerging from sub-space. Their dangerous potential has caught the attention of rebel factions as well as the ruling Commonwealth. When contact with her kind turns pilots into casualties, the Governors fear an imminent invasion engineered by their rebel enemies. Pursued by Air Command, Seth heads deep into rebel-controlled territory to recover the stolen entities and keep this deadly weapon from falling into the wrong hands. Things get personal when his alien visitor begins to transform his mind and his life, turning the rescue mission into a fight for survival for all of them.

Air Command pilot Nova Whiteside is assigned to a remote outpost to guard a new orbiter against sabotage. When she is trapped behind enemy lines in a bloody uprising she meets Djari, a civilian whose trust in the governing Union is shattered by what he has witnessed. When she uncovers the treacherous and illicit schemes taking place , it seems that local wars are the least of her troubles.

Ships are disappearing in subspace. Traders, rebels, pirates, and even military vessels are losing their way in the Big Nothing that makes space travel possible. Deep-cover agent Sethran Kada joins the investigation after his own navigator, Ciela, barely escapes the void with her mind intact. It soon becomes clear that this subspace trap is more than some natural phenomenon, Seth’s search for answers leads him to a brutal penal colony on the brink of revolt, and uncovers a plot to destroy an entire planet. When evidence points to the return of the dangerous subspace entities known as Dyads, Air Command mobilizes to annihilate the threat at any cost. Seth and Ciela pursue a Dyad who has infiltrated a key research complex where they discover that the inexorable subspace peril will not just threaten a single planet. It will mean the end of interstellar travel and destroy their Commonwealth civilization.

Seth Kada, a deep-cover agent working for the Commonwealth, has tracked a group of rebels to the remote Tayako Orbiter. But before he can seize them, the rebels are captured by a powerful rival faction and spirited away. Seth manages to re-capture one of the rebels, a subspace navigator named Ciela, and soon realizes that her crew's origin and purpose are far more pivotal than anyone could have suspected. Caught up in a violent clash between rebel factions, Seth and Ciela's divergent loyalties must be put aside to prevent the destruction of a peaceful civilization - and find her people before their ultimate destiny is realized.

Captain Nova Whiteside receives new technology designed to change the dynamics of the Commonwealth wars. Enemy factions conspire and so Nova finds herself aboard a rebel ship where her value as hostage isn't nearly as great as her value as a defector. Also suspected of collaboration, her Delphian Vanguard partner Tychon sets out to track her down. He discovers a puzzling piece of Nova's past when a motley alliance of strangers comes to his aid and their search leads him deep into rebel territory. When the full consequences of the rebels' ambitions become clear, far removed from the intervention of Air Command, Tychon and Nova are forced to consider the unthinkable.
