Publisher's summary
The TARDIS materialises on board a still and eerie spaceship. When a squad of soldiers land, they realise they've found themselves in the middle of a war zone. With one of their crew trapped by the enemy, the Doctor and his friends find themselves locked in a desperate race for survival. Vast warships manoeuvre around each other as both sides try to out-think their opponents, flying into ever more dangerous areas of space.

The stakes could not be higher. But as ever in war, the lines between good and evil are hard to define. Will anyone survive to claim the moral high ground?

Ship of Death (1)
The TARDIS lands on a spaceship adrift in space. As they explore, the travellers find a corpse inside a room, several machines measuring the quality of the atmosphere and a nebula outside the ship, looking thick and dangerous. They hear a radio message for the ship they are in, the Vanguard, and try to come back and leave, but the doors through which they passed are now closed. They are reached by a group of men led by Toban, calling themselves the "Last Born", and Barbara and Susan are driven away to their other ship, the Endurance, while the Doctor and Ian stay with the group to help them in their exploration.

Aboard the ship, Susan and Barbara are examined by the medical officer, Olivan, and are identified as "organics", i.e. made of flesh and blood. From Benya, another member of the party, and Myla, their leader, they learn they have encountered a race of syntethic beings, exploited for labour for a hundred year by the "Shifts", a sort of genetic vampires. They are sent into "the Bridge", as they call the nebula, to search for energy; as they did so, they also charted it in search of a way to escape their jailers and finally stole two ships when they were sure. The same thing is told to the Doctor and Ian by Toben, as he also explains the people aboard the Vanguard carried the map through the Bridge; when they lost contact, Toben and the others came here to see what happened, and try to recover the map if possible.

Toben's party is ambushed and captured by the Shifts, reptiloid lifeforms capable of changing forms, and they are killed except for Toben, Ian and the Doctor. Their leader, Arran, explains they did attack the ship, but even after killing the other party they were not sure which parts of it were secure; they observed the arrival of the travellers and followed them in order to be sure. He questions the prisoner about the TARDIS, but none of them answers. As he is about to become violent, Benya arrive in their aid with other men (sent by Myla), Barbara and Susan; they manage to free the prisoners, but Arran captures Barbara and locks them out of the control room as he prepares to open the windows and depressurize the ship, killing them all. Ian wants to go back for Barbara, but he is persuaded by the Doctor to first try and save himself.
