'The Brigadier's going to shoot you, Jo,' the Doctor said grimly, 'and then he's going to shoot me. Both of us are going to die.'

The Doctor builds a machine designed to predict the future. It shows the Brigadier murdering him and Jo in cold blood. Unable to tell where or when this event is destined to occur, the Doctor and Jo decide that they must stay apart.

Jo is sent on a top-secret mission to the war-torn Arab nation of Kebiria. But upon arrival, she is immediately arrested and consigned to a brutal political prison. The Kebirians have something to hide: deep in the North African desert, an alien infestation is rapidly growing. And the Doctor and UNIT soon discover that unless it is stopped, the alien presence will spread to overrun the entire world.

Sam is on her own, but her distance from the Doctor doesn't make for a trouble-free life.  Rescued from an out-of-control spaceship, she finds herself on a tiny moon which is the only known source of dreamstone, a mysterious crystalline substance that can preserve your dreams - or give you nightmares.

Pitched into the middle of a conflict between the mining company extracting dreamstone and ecological protesters, Sam thinks it's easy to decide who the good guys are - until people start dying, and the killers seem to be the same species as some of her new friends.

Meanwhile, the Doctor has tracked Sam down, but before he can reach her he's co-opted by the Dreamstone Mining Company and their sinister military advisers.  Suddenly, it's war - and the Doctor is forced to fight against what he believes in.  He alone suspects that dreamstone isn't what it appears to be.  But nobody's listening - and nobody could dream who the real enemy is...

'I am going to make you immortal.'

Bored with her job, bored with being perpetually skint, Bernice Summerfield leaps at the chance of a free holiday arranged by her new friend Maeve Ruthven, St Oscar's Professor of Comparative Religion.

But all is not what it seems.

Benny's holiday rapidly goes from bad to worse to downright dangerous. For a start, the 'luxury cruise' is a religious pilgrimage, and alcohol is forbidden to those on board. Then she is attacked, badly injured and confined to a wheelchair.

And that's before the murder.

Benny finds herself caught in a web of intrigue - not knowing who on board can be trusted or which way to turn. And with the future of more than one world depending on her actions, she must decide who to believe, expose the hidden killer and prevent a ruthless grab for power.

Years after leaving UNIT, Jo Grant receives a plea for help from an old acquaintance. A paleontological study of the earliest known humans is apparently under threat from a UNIT force lead by a captain that does not officially exist. Investigating further, she begins to find herself out of her depth - and out of the twentieth century altogether...

Meanwhile the Doctor and Sam visit Earth in 2109 - but there is no trace of the human race. Earth is the home of the Tractites, a peaceful race who have been living there for hundreds and thousands of years. Astonished and appalled, the Doctor travels back in time to see just what went wrong in Earth's pre-history.

Why have Jo and the expedition been taken back in time? Are the Tractites all they seem? Finally, separated from the TARDIS, the Doctor's last chance to put things right rests with Sam - but has even she turned against him?

"I think time and space just fell apart."

Anji isn't sure, but then it's hard to be sure of anything now. Good Times Inc. promised a new tourist experience, with hotels in every major period of human history - but that kind of arrogance comes with a price, and it's a price the Doctor doesn't want to pay.

As aliens conquer an alternative Earth, Anji and Fitz race to find out how to stop Good Times without stopping time itself - but they find that events are out of control; they can't even save each other. When the Doctor tries to help, it gets far worse. At the Last Resort, only Sabbath can save the day. And then the price gets even higher…

This is another in the series of original adventures for the Eighth Doctor.

1967: The Revolution has just started. All you need is love - but the ability to bend space and time helps. An entity called the Revolution Man is writing his graffiti across the surface of the Earth, using a drug called Om-Tsor.

Trouble is, none of this was supposed to happen. The Doctor knows that the Revolution Man isn't for real, that he's part of the problem, not part of the solution. But how is he going to convince the flower children? How is he going to convince Sam? And he doesn't dare tell Fitz...

1968: The Chinese People's Army want to defeat the capitalists. Om-Tsor is the most powerful means available, and the source is on their doorstep. If half of India is immolated - well you can't make an omelette without breaking eggs...

1969: The Revolution Man has decided. Mankind is evil, not good. The only way forward is to destroy all of it. The Doctor and Sam struggle to find him but time is running out...

Take a TARDIS trip through the constellations, as the Doctor travels to twelve thrilling tales inspired by the mystical zodiac.

Telepathic fish, miniature lions and twin planets are the least of his problems, as the Doctor all eight of him faces the Capricorn Killer, endures a mindswap with the Machiavellian Master, and dances with Death herself.

And that's not the half of it as the two K9s can attest.

This collection features twelve exclusive short- stories from well-known names in Doctor Who fiction including acclaimed novelist and Booker nominee Paul Magrs, alongside Simon A Forward, Mark Michalowski, Paul Leonard and Joseph Lidster as well as fresh new voices.

'Children make better soldiers,' said the teddy bear. 'They kill without compunction.'

The Doctor and Benny are following a trail of kidnapped children across Europe, a continent recovering from the ravages of the First World War. The only clue they find is the toy bear each missing child was given. But someone is aware of their search, and they soon find themselves unwilling guests on the planet Q'ell, where a similar war still rages - and has done for fourteen hundred years.

Stranded on Earth, Chris Cwej and Roslyn Forrester struggle to find a way of stopping the Q'ell from recruiting every child in the world to their cause. And the Doctor tries to start a peaceful revolution on a planet where there is no longer any word for peace.

The Second World War is drawing to a close.  Alan Turing, the code-breaker who has been critical to the allied war effort, is called in to break a mysterious new cypher.  It's coming from Germany, and everyone assumes that it is German - everyone except Turing's new friend, the Doctor.  Indeed is seems the Doctor knows too much about the code, and the code-makers - and when people start to die, even Turing wonders if the Doctor is the one to blame.

Graham Greene, novelist and spymaster, has also encountered the Doctor, and thinks he's a rum enough chap, but in a remote African village he has encountered something far stranger.

To find out the truth, they must cross the front line and travel through occupied Germany - right into the firing line of the bloodiest war in history.  What they find there has no human explanation - and only the Doctor has the answers.  Or maybe they're just more questions…

'You want me to help you eat your children?' Ian said. Jellenhut's eye-stalks twitched. 'How else would we remember them?'

Venus is dying. When the Doctor, Barbara and Ian arrive they find an ancient and utterly alien civilization on the verge of oblivion. War is brewing between those who are determined to accept death, and those desperate for salvation whatever the cost.

Then a spacefaring race arrives, offering to rescue the Venusians by moving them all to Earth - three billion years before mankind is due to evolve. Are the newcomers' motives as pure as they appear? And will the Doctor allow them to save his oldest friends by sacrificing the future of humanity?
