Summary 
From the book jacket
The planet Kirlos – an artificial world built by a mysterious long-dead race called the Ariantu. Kirlos is now home to many races from both the Federation and the K'vin Hegemony, who have enjoyed years of peaceful co-existence and profitable trade. The planet also hold a wealth of undiscovered archaeological treasures, which the  and its crew are dispatched to help uncover.

Sent to the surface to assist an archaeological team, Geordi, Data, and Worf soon find themselves cut off from the Enterprise – and the prime suspects in a series of terrorist attacks. The three Enterprise crewmen are imprisoned, relations between the K'vin and the Federation begin to crumble, and Kirlos' ancient underground machinery awakens from a centuries long dormancy, primed to release the most powerful destructive force ever known.

"I learned that I need to try and keep cooler in high-pressure situations… and maybe find a way to keep my VISOR on tighter."
"I have learned that if I had been allowed to shoot things when I wanted to shoot them in the first place, we would have had significantly fewer problems."

Background information 
 The concept of a collaboratively-written Star Trek novel originated from a gathering of New York-based Trek authors organised by Pocket Books editor, Dave Stern, to which Greenberger was invited along as a consequence of his work editing DC Comics' Trek output. A previous meeting had derived the concept for The Lost Years series, and it was at the  event that the idea of a group of authors working on a single novel was suggested. (; Doomsday World Author's Notes)
 Greenberger agreed with the idea, and developed the concept for the story. The novel was deliberately structured so that characters were split up, allowing each author to work on a different plotline. After working through the completed draft together, Friedman then gave the novel a final polish. ()
 The success of this novel led to a second collaboration, the Pocket TOS novel, The Disinherited (although Carter decided not to take part).
