Star Trek
The Next Generation: Book 2: Peacekeepers

Exploring a deserted alien spaceship, Lt. Commander Data and Lt. Geordi LaForge suddenly find themselves transported light-years away - into the arms of a suspicious, fearful mob! While Captain Picard and the crew of the Enterprise search feverishly for the missing crewmen, Data and LaForge discover they are in a station almost identical to the one they were exploring, high in orbit around an earth-type world. Years before, the occupants of that planet accidentally stumbled onto the ship and its advanced technology - and since then, have used its weapons to keep the nations on the planet below disarmed, and at peace. But now, a breakdown in the station's technology threatens their survival. Somehow, Data and LaForge must find a way to restore trust between the planet below and the station's guardians up above - before a final, destructive war breaks out!
