Search Worlds Without End

In the days when the Time Lords were young, their war with the Vampires cost trillions of lives on countless worlds. Now the Vampires have been sighted again, in San Francisco. The Doctor, aided by Sam, must find a way to stop them.

The Doctor and Sam have been separated. Landing on Haolem, Sam finds herself employed by INC, a company that dominates the planet and one of its major employers. Sam learns that decisions and actions can be made as fast as INC employees think. Is this a workforce of computerized zombies?

The Doctor regenerated in San Francisco at the turn of the millennium. When he returns there a few years later, it seems the catastrophic events that nearly sent the whole of Earth into cosmic oblivion have taken their toll. San Francisco was the anchor point, and a breach between dimensions has sprung up. All sorts of weird and wonderful creatures have turned up -- griffins, unicorns -- and things more sinister.

The Doctor's companion Sam is exposed and becomes a changed person -- literally. Her hair is dark, she has never met the Doctor in her life. With Fitz, he is able to convince her to help them put things right -- to sacrifice herself so that the old Sam may return. For stalking the turbulent streets is the sinister Unnaturalist -- a collector of genetic curios whose private collection will be much enriched by the Time Travelers.

The Doctor has been staying on the planet Hitchemus for the past few months where he has been learning to play the violin from gifted young composer Karl Hassan. Hitchemus is a planet with two distinctive features -- the humans who live there have a formidable reputation for composing, playing and appreciating a wide range of music -- while its tiger population is showing unusual signs of intelligence.

Although Anji is greatly unnerved by the sight of a tiger taking a book out of a library, no one is prepared for the day when the tigers take over the planet. Their demands are unusual though -- they want to be taught to play instruments as well as the humans, and to this end kidnap all of the planet's most eminent musicians.

Why are these tigers so intellectually advanced, and can the population of Hitchemus resolve their conflict to avoid civil war? The Doctor sympathises with the tigers and humans alike, but needs to help both parties to resolve their differences before they both begin to see him as a traitor...
