The Time War. The Doctor has been injured and brought to a Time Lord field hospital. His body glows with energy, but this is no regeneration into a future form - instead, the Doctor's past faces begin to appear as he flits haphazardly between incarnations... Staggering to his TARDIS, the Doctor sets out to solve the mystery of his 'degeneration'. Who has done this to him? How? And why? From the Earth to the stars, across an array of familiar times and places, he follows clues to retrace his steps, encountering old friends and enemies along the way. Tumbling through his lives, the Doctor must stop his degeneration before he loses himself completely... Settling as his Fourth incarnation, the Doctor goes in search of the Monk, with a vague memory that he had something to do with his 'degeneration'. On Earth, the Monk is meddling, bringing Sarah Jane Smith to the future UNIT HQ to steal a device for an alien race. The Doctor must help Kate Stewart and Osgood foil an invasion before he can confront the Monk about what he knows...

This superb collection of stories by some of today's finest genre writers are each set along Britain's northern coast -- Whitby, Scarborough and other traditional English seaside resorts -- where tales both grim and delicious are forged.

A space station orbiting Earth has lain dormant for 8,476 years. Its systems are clogged with dust, so the human crew kept frozen in cryogenic storage have never woken up. When the Doctor, Sarah and Harry arrive to resuscitate the sleepers, they discover something else on board. A small, golf-ball like object gives Harry an electric shock, and has a more sinister impact on the awakening crew. Soon, the Doctor and his friends are battling to save the space station - and Earth - from a ravenous puffball! CAST: Tom Baker (The Doctor), Sadie Miller (Sarah Jane Smith), Christopher Naylor (Harry Sullivan), Yasmin Mwanza (Viva) Lara Lemon (Den), Terry Molloy (Narib / Noah), Nicholas Khan (Vez / Kol), Cameron Johnson (Mek).
