Doctor Who: Terminus

by John Lydecker & Stephen Gallagher. 

When the TARDIS is sabotaged and becomes dimensionally unstable, its internal fabric begins to dissolve, and Nyssa is drawn into a junction with a strangely deserted spacecraft. 

The Doctor, Tegan and Turlough follow in pursuit, and discover the shocking purpose of Terminus. The Doctor forms an uneasy alliance with two space pirates, whilst Tegan and Turlough become frighteningly enmeshed in the spaceship's infrastructure. 

For Nyssa, meanwhile, the nature of a sudden illness which engulfs her will have life changing consequences.
