Publisher's summary
The entire Seventh Fleet has disappeared. The Commander says it is impossible. K9 says that is only because the human mind cannot understand it. At just under the speed of light, he takes off across the deep starless gulf between the galaxies on another dangerous mission. He uses a battlecruiser as his bait — but first he must find the trap. ..

Continuity

 * Omegon may in fact be Omega, and there is a possible reference to the events of The Three Doctors.
 * K9 is described as working for the Time Lords, which suggests that the story takes place some time after the events of The Invasion of Time. Presumably the other three books in the series continue from this continuity.
 * This book introduces the space vessel K-NEL which would be referenced throughout the series.
