'To lose one set of memories may be regarded as a misfortune.  To lose two smacks of carlessness.'

The Terran colony world of Espero seems the unlikely source of a sophisticated distress call.  And the Doctor, Fitz and Trix are not the only ones responding to it.

While Fitz consorts with royalty, the Doctor's on the run with a 16-year-old girl, and Trix meets a small boy with a dark secret.

In a race for the minds and souls of an entire planet, the Doctor and Trix are offered temptations that may change them forever.

At least one of them will be unable to resist.

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

'Do Time Lords get Alzheimer's disease?' asked Ace.  'Oh, we get far worse things than that Ace.  The dementias that plague ua are much, much darker.'

Collecting his mail in the London of 2012, the Doctor and Ace a called through time to south-seat Scotland to help out an old friend - an old friend who's vanished.  They find themselves at Graystairs, an Alzheimer's clinic and a place of healing, where the patients seem to be gaining a new lease on life.  But whose life is it?

Why is the Doctor so reluctant to reveal what happened in the TARDIS before their arrival?  Why are cats and dogs - not to mention people - disappearing?  Who is the shadowy figure stalking the Doctor and Ace?  And what is the secret of the mysterious Miss Chambers, whom no-one remembers meeting?

Soon the Doctor and Ace find out  the hard way that actions have consequences - and that there's more than one kind of dementia.

Wanted: attractive young girl (boy may be considered). Must have strong ankles, healthy lungs, and no family ties. Ability to say 'what's that, Doctor?' in many different ways a necessity. Bizarre taste in clothes may be an advantage. Must be able to deal with traumatic situations involving life and death with no obvious after effects.

They didn't always ask to travel with the Doctor. And even if they did, they didn't know what the consequences would be.

Were Ian's travels foretold? What paradoxical conundrums faced the Doctor, Charley and Will Shakespeare in Ancient Troy? And just how difficult is it to get a job when you can't account for a gap of several years on your CV?

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.
