Publisher's summary
One Time Travelling Doctor - Two Thrilling Adventures

In The Web In Space, a distress signal calls the TARDIS to the Black Horizon, a spaceship under attack from the Empire of Eternal Victory. But the robotic scavengers are the least of the Doctor's worries. Something terrifying is waiting to trap him in space...

And in Terminal of Despair, the TARDIS crew is quarantined in Terminal 4000, where the hideous Desponds have destroyed the hopes of all awaiting passengers. Can the Doctor and his friends help them escape without succumbing to despair themselves?
