GO TO GUNS!

The bearlike Karbarrans and the swashbuckling amazons from Praxis, the feral natives of Garuda and the Human Robotech heroes - these oddly met champions banded together with other races, from other planets, to form the Sentinels.

Yet what fighting force could hope to dislodge the Invid hordes from Haydon IV, ethereal world of superscience and hidden emotional conflict; or Spheris, crystalline globe of living minerals and murderous resonances?

The Sentinels launch their attack nevertheless; they've come too far to surrender to tyranny.  But the treachery of a megalomaniac Human general and a mutating Invid P.O.W. make the war seem hopeless.

The Sentinels battle on, though, because for them it's...

VICTORY OR DEATH!

'Doctor!' said Anji.  This couldn't be happening, he couldn't just walk out on them!  'Look, give them a chance, they're frightened, they're only -'

'Human?'  He took a deep breath, as though to stop himself from saying anything more.  'Now stay!'

The weather is going to hell.  The tigers are coming to town.  And the Doctor has taken his violin and vanished.

The island world of Hitchemus is home to a colony of musicians and seemingly harmless alien animals.  When the storms and the tigers break loose, the Doctor tries to protect the humans - but the humans don't want him.  When he ventures into the wilderness in search of the tigers' secrets, Fitz and Anji find themselves on their own, trying to prevent war.

With both sides eager for blood, and hurricanes on the horizon, the Doctor must decide whether this time he's on the side of the human race.

'Good morning. We're doomed. Would you like a cup of tea?'

On the far side of a break in the fabric of space is the planet Zamper, home of a secretive organization that constructs and sells the mightiest warships in the galaxy. It is to Zamper that the last warriors of the fallen Chelonian Empire have come in a final attempt to restore their race's glory.

Separated from the TARDIS, the Doctor and his companions are intrigued by the bizarre operations on Zamper. Why are accidents and power failures afflicting the planet? What is the true agenda of the mysterious Management? And what are the strange powers of the alien shipbuilders?

'You've decided to concentrate on deriving energy from the kinetic force of planetary movement...'

A glib remark from the Doctor to a desperate scientist has had far-reaching effects on the empire of Morestra.  Eminent Morestran scientist Sorenson, attempting to find a new power source for his planet, risked a universal catastrophe by attempting to steal anti-matter crystals from the distant planet Zeta Minor.  The Doctor averted disaster, but has in effect sent all Morestra up a technological cul-de-sac.

Now in his fifth regeneration, the Doctor becomes involved once again in Morestra's future.  The empire has become a theocracy, and the all-powerful Church, finally discovering that Sorenson's world-spanning energy tower will never work, is attempting to save face by covertly returning to Zeta Minor to steal the powerful minerals they need.  This time, they believe they are prepared for all eventualities...

With his companions embroiled in ever-shifting loyalties and intrigues of the Morestran court, only the Doctor accepts that the forces of the anti-matter universe can never interact with our own.  Can he stop something he started two thousand years ago?
