Colsec 02 - The Caves of Klydor

One piece of equipment that had stayed relatively intact was Guide, a data-storage computer that had come to be almost a sixth member of the group. And Guide gave them a piece of frightening news: it had picked up a signal from this new region of Klydor—a signal that could come only from an Earth spacecraft. It had to mean that ColSec agents were on Klydor.

But who it really is in that spacecraft, and why they are there, turns out to be even more startling and frightening. The young people find themselves embroiled in a new battle for survival, which also has at stake the continuation of a rebel uprising against the Organization. In this action-packed sequel to Exiles of ColSec, Douglas Hill once again proves himself a master of spine-tingling, fast-paced science fiction.
