Publisher's summary
A new adventure in time and space for the Fifth Doctor and his new companion, Amy, as they search for the Key to Time.

On a planet where Time stands still, the Doctor meets a woman who is just a few minutes old. She is a Tracer, sent into our Universe by her makers to locate the six segments of the Key to Time. This being without a name wants the Doctor to be her assistant, but she doesn’t tell him the whole truth. Not at first.

Their first port of call is Mars, where a society that one day will become Ice Warriors lives in peace and civility. But the Doctor’s arrival will change all that. The universe is dying, a choice must be made, and the Judgement of Isskar will be declared. The price must be paid - even if it takes centuries…

 * Following the destruction of Mars' atmosphere, the Ice Warriors fled to Deimos, one of the planet's moons, where they constructed catacombs and placed themselves in suspended animation in the hope of one day either reclaiming Mars or conquering Earth. Millions of years later, after Mars had been colonised by humans, large sections of the catacombs were open to the public in the museum in the Deimos moonbase in the 23rd century. (AUDIO: Deimos)
