Doctor Who: The Fifth Doctor Adventures - Shock and Awe

The Doctor and Nyssa face alien menaces on Earth and on a far-off unnamed world. Contains two new adventures starring Peter Davison and Sarah Sutton.

Lair of the Voltaxa by Roland Moore. 

The time travellers’ plans for a break in Devon are disrupted by a report of a car ‘coming to life’ and attacking someone. The Doctor suspects a link to the ‘Miri Cube’ – a sentient gadget soon to be launched nationwide. Technology that is decades ahead of its time. But the cubes contain a disturbing secret – an alien intellect is preparing its plans for conquest.

March of the Colossus by Alan Ronald.

On a beautiful, unspoiled world, the Doctor and Nyssa meet the Dianasa, a primitive tribe who await Arrival Day, when the giant deity that protects them will descend from the sky. An intriguing myth. Except the Colossus is real, as a ruthless off-worlder has discovered. And he will stop at nothing to exploit this discovery for his own ends.
