According to popular legend, the great humanitarian Stewart Ransom founded the Independent Earth Colony on Axista Four in the year 2439, but the truth is not as neat and simple as the legend would suggest...

The year is 2539.  Arriving on Axista Four the Doctor, Zoe and Jamie find the colony in a state of chaos.  A breakaway group of colonists - the 'Realists' - has abandoned Ransom's Back to Basics ideals and is creating a new high-tech settlement.  The 'Loyalists' who remain are dwindling in number and face total extinction.

Meanwhile, a spaceship from Earth has arrived with news that 80,000 refugees are about to descend upon the planet; the Realists are staging raids on the wreck of the colony ship, and in a secret underground bunker mysterious aliens who claim to be the planet's first colonists are beginning to awake.

Who are the dog-like aliens who call themselves Tyrenians?  What is the secret agenda of the sinister Federation Administrator Greene?  And what really happened when the colony ship crash-landed on Axista Four 100 years ago?

This adventure features the Second Doctor, Zoe and Jamie and the Seventh Doctor and Ace.

Ten Stories - Seven Doctors - One Chain of Events

'The consequences of having the Doctor crashing around our universe can be colossal... The Doctor is a time traveller.  Never forget that, because it is central to an understanding of what makes him so terribly dangerous.  Most of us, in our tiny, individual ways are involved in the writing of history.  Only the Doctor is out there rewriting it.'

But even the Doctor may not see the threads that bind the universe together.  Perhaps, instead, he cuts right through them.  Who knows what events he sets in motion without even realizing?  Who knows what consequences may come back - or forward - to haunt him?

Ten completely new tales from the universe of Doctor Who.  Seven Doctors' lives, inexorably linked in a breathtaking chain of consequences.

As always, the editors have assembled a dazzling array of writing talent, from award winning TV script writers to acclaimed New Adventures authors.  And, as before, there are the usual contributions from talented new writers.

'You know me then?' asked the Doctor, a little tentatively.  'You're the Doctor,' replied Fitz, a slight frown worming its way onto his forehead.  'Yes, yes, yes, the Doctor, of course I am.'  The Doctor smiled, genuinely pleased to see a familiar face, even if for the moment he couldn't quite put a name to it.  'But, er, Doctor who?' he added hopefully.

The Doctor and Fitz are back together at last, but the Doctor is not the man he once was - which is a shame, because Fitz has promised Anji Kapoor that his old friend is Anji's best hope of finding her alien-abducted boyfriend, Dave.

Soon the Doctor, Fitz and Anji find themselves involved in a desperate contest between Pierre-Yves Dudoin and Arthur Tyler the Third, each determined to be the first privately funded man in space.  But not all the parties are playing fairly; members of an alien race called the Kulan are helping the Frenchman - and at the far reaches of the Solar System their battle fleet awaits...

Can the Doctor find Dave before the alien contact proves fatal?  Who are the secret agents keeping tabs on the rival Space Race teams?  Will the Doctor's mysterious blue box finally reveal its purpose?  And does the Doctor, now truly a man without a past, have what it takes to stop the Kulan Invasion of Earth...?
