Cover blurb: When Zoe reattaches an old piece of equipment to the TARDIS console, she, Jamie and the Doctor are very lucky to avoid a collision.
But the place they find themselves in may be even more dangerous — because there they encounter another Doctor, a space pilot named Steven... and a young woman called Katarina — who really shouldn’t be there....
