Four new adventures featuring the Fifth Doctor and Turlough!
A young woman climbs a perilous mountain in search of her destiny. The Doctor and Turlough save her from the monsters on her trail – but what awaits them in the Cavern of Becoming is stranger, even, than the ravening Hungerers outside.
- The Doctor refers to the fact that the Tractator invasion of Trion etched itself onto the racial memory of the Trions. (Frontios)
