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 for harboring the alien, 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. Quantum Tangle is part of Chris Reher's Targon Tales series but does not intersect the other stories. Sethran Kada previously appeared in The Catalyst and also in Rebel Alliances.

By the author of The Catalyst and Quantum Tangle 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.

By the author of Quantum Tangle and Sky Hunter. 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.
