There’s likely no more of a thankless job in the Federation than temporal investigation. While starship explorers get to live the human adventure of traveling to other times and realities, it’s up to the dedicated agents of the Federation Department of Temporal Investigations to deal with the consequences to the timestream that the rest of the Galaxy has to live with day by day. But when history as we know it could be wiped out at any moment by time warriors from the future, misused relics of ancient races, or accident-prone starships, only the most disciplined, obsessive, and unimaginative government employees have what it takes to face the existential uncertainty of it all on a daily basis . . . and still stay sane enough to complete their assignments. That’s where Agents Lucsly and Dulmur come in—stalwart and unflappable, these men are the Federation’s unsung anchors in a chaotic universe. Together with their colleagues in the DTI—and with the help and sometimes hindrance of Starfleet’s finest—they do what they can to keep the timestream, or at least the paperwork, as neat and orderly as they are. But when a series of escalating temporal incursions threatens to open a new front of the history-spanning Temporal Cold War in the twenty-fourth century, Agents Lucsly and Dulmur will need all their investigative skill and unbending determination to stop those who wish to rewrite the past for their own advantage, and to keep the present and the future from devolving into the kind of chaos they really, really hate.

The agents of the Department of Temporal Investigations are assigned to look into an anomaly that has appeared deep in Federation territory. It's difficult to get clear readings, but a mysterious inactive vessel lies at the heart of the anomaly, one outfitted with some sort of temporal drive disrupting space-time and subspace. To the agents' shock, the ship bears a striking resemblance to a Constitution-class starship, and its warp signature matches that of the original Federation starship Enterprise NCC-1701—the ship of James T. Kirk, that infamous bogeyman of temporal investigators, whose record of violations is held up by DTI agents as a cautionary tale for Starfleet recklessness toward history. But the vessel's hull markings identify it as Timeship Two, belonging to none other than the DTI itself. At first, Agents Lucsly and Dulmur assume the ship is from some other timeline . . . but its quantum signature confirms that it came from their own past, despite the fact that the DTI never possessed such a timeship. While the anomaly is closely monitored, Lucsly and Dulmur must search for answers in the history of Kirk's Enterprise and its many encounters with time travel—a series of events with direct ties to the origins of the DTI itself...
