Cover blurb:
A genius maths nerd, a weird webzine publisher, and the Doctor’s old ally, the Brigadier find themselves helping the Doctor and Ace solve what should be a simple puzzle: the appearance of a crop circle in the Kentish countryside. Hardly uncommon. But there are some peculiar features. It’s not a circle but a series of square-sided shapes. It’s filled with ice. And it draws the Doctor and Ace into a confrontation with a reality right next to zero. This adventure features the Seventh Doctor and Ace. |
