Publisher's description

An all new Star Trek e-novella from the world of Deep Space Nine, featuring the fan-favorite Federation bureau the Department of Temporal Investigations!
The dedicated agents of the Federation Department of Temporal Investigations have their work cut out for them protecting the course of history from the dangers of time travel. But the galaxy is littered with artifacts that, in the wrong hands, could threaten reality. One of the DTI's most crucial jobs is to track down these objects and lock them safely away in the Federation’s most secret and secure facility. As it happens, Agent Gariff Lucsly and his supervisor, DTI director Laarin Andos, are charged with handling a mysterious space-time portal device discovered by Starfleet. But this device turns out to be a Trojan horse, linking to a pocket dimension and a dangerous group of raiders determined to steal some of the most powerful temporal artifacts ever known...
