This novel is set rather uniquely between Genesis of the Daleks and Revenge of the Cybermen; it takes place during their Time Ring travels just after Genesis of the Daleks. Since the Doctor remains separated from his TARDIS from the beginning of former serial to the end of the latter serial, this story sees him borrowing another one temporarily.
It was not the only story to take place between the two serials. The Short Trips entry The Last Thing You Ever See also saw the Doctor, Sarah and Harry travelling by time ring while trying to return to Nerva Beacon. Logically, that story chronologically follows this one.
Publisher's summary Edit
Sarah is marooned on a slave world where the only escape is death. Harry is caught in the middle of an interplanetary invasion, and has to combine medicine with a desperate mission. And the Fourth Doctor lands on a world so secret it does not even have a name.

The Doctor Edit
- The Time Lords give the Doctor another TARDIS, one with a functioning chameleon circuit, but he gives it back.
- The Doctor mentions adventures with the Daleks, the Aztecs, Atlanteans, the London Underground, the Peladon and the Minoan labyrinth of Crete.
- The Time Lords give the Doctor a second Time Ring, and this takes the Doctor, Harry and Sarah Jane to Nerva Beacon.
Time travel Edit
- After departing from Skaro, the Doctor, Sarah and Harry are scattered across the Adelphine Cluster due to temporal disruption interfering with the Time Ring.
- The prologue of the novel contains explicit confirmation that the Doctor's mission in Genesis of the Daleks created a new timeline. The Time Lords actively monitor the changes as thousands of worlds are retroactively liberated from the Dalek Empire, although millions more remain under Dalek rule. The concept of a second timeline in Dalek history branching off from Genesis was introduced in The Discontinuity Guide, as reprinted on the BBC website.
- According to the Time Lords, due to the Doctor's actions, a force of robots will arise that will contribute to the fall of the Daleks. It is implied that these robots are the Movellans.
