Crisis in Space (novel)

US Edition
The Doctor needs YOU to save the galaxy from the bizarre manipulations of a madman in Crisis in Space.

The Doctor's assistant, Turlough, intercepts a message from Outer Space. Garth Hadeez, the Overlord of the gruesome Golons, has instructed his slaves, the midnight-black Neroids, to release a new planet into the Solar System.

But the planet is a fake. Designed to resemble Phobos, one of Mars's tiny twin satellites, it is actually a Black Hole capable of annihilating the entire Solar System.

YOU will join the Doctor's team in the struggle to save the Cosmos. Important decisions are yours to make as you Find Your Fate.
