Search Worlds Without End

"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?

"The Brigadier's going to shoot you, Jo," the Third 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.

"Those who are intelligent, strong and virtuous are promoted. The stupid, the weak and the unworthy will die. How else is it possible for the world to make progress?"

The TARDIS lands on Nooma, a world in the middle of an industrial revolution. But the Third Doctor, Jo and Mike Yates quickly discover that there is no limit to the upheaval. The sky is alive, and at war with the ground. The continents are on the move, competing for a place under the sun. And somewhere, there is a starship...

Mike finds himself committed to a fight where his only option is to kill or be killed. Jo is caught in a workers' revolt. And the Doctor must find out what is really happening to Nooma before the struggle for survival kills the world and everyone on it.
