Doctor Who Books: BBC Classic Series Books

Peri hasn't been time-travelling for long and is just getting used to the Doctor and the TARDIS. The Doctor's such a sweet, friendly guy and the TARDIS keeps leaving her little presents, which is neat. When the TARDIS takes them to a party of super-advanced humans on a pleasure-planetoid in the far future (even neater!), Peri falls for the charms of the local hunk and finds herself flying headlong into a quite different form of time-travel...

Far out in space, on the ragged edges of Earth's bloated empire, an elite unit of soldiers is on a training mission. But deep in the heart of the hollowed-out planetoid that forms their battleground, a chilling secret waits to be discovered: ten alien corpses, frozen in time at the moment of violent, bloody death.

It doesn't take the creation of a whole new universe just to kill a cat.'

The fuse has been lit. Reality has been blown apart, and the barriers that shield our universe from the endless others running parallel have shattered with it. The only chance the Doctor has of saving the multiverse from total collapse is if he can get back to Earth where the damage was first done - and put things right.

Millennia ago, the great god Valdemar held sway over the universe. Somehow the Old Ones defeated this dark presence and entombed him beneath the acid skies of Ashkella, before disappearing themselves for ever.

Imagine a world where death has meaning, where God exists and faith is untested. Where people die with the purpose of their lives made clear to them in blissful understanding. Such a world exists, hidden on the far side of the universe where a battered blue police box has just faded into being...

Jo Grant had no inkling of the ship that revolved in orbit like a discreet, preposterous thought in the mind of someone serene but bonkers.

The Doctor is repairing the TARDIS systems once again when it is swept up by a garbage ship roving through space, the Quetzel.
