Publisher's summary
Inside a cluster of fused-together derelict spaceships, four of the Doctor's oldest friends — and one of his newest ones — are lost and confused. They don't know how they got there or what they're meant to be doing — but as the place is infested with Daleks, Sontarans and dinosaurs, their first priority is staying alive.

To their collective relief, the Doctor turns up and has a reasonable idea of what's going on. If the six of them work together, they can escape this place and get home. But, unexpectedly, others may be working together to ensure they all die here...

Species

 * A Tyrannosaurus rex is transported to the alternative Death Zone, where it kills several Daleks before it is exterminated.

Technology

 * The Sontaran ship is provided with dwarf star alloy and a tractor beam.

Continuity

 * Ian and Steven previously met in the Mechonoid City on Mechanus. (TV: The Chase)
 * Ian sets a trap for a Dalek by placing a sheet of metal on the floor in the hopes of disrupting the static electricity supply by which they are powered and subsequently disguises himself as a Dalek. He did both of these in his first encounter with them on Skaro. (TV: The Daleks)
 * Ian, (TV: The Daleks, The Dalek Invasion of Earth, The Chase) Steven, (AUDIO: Across the Darkened City, The Dalek Occupation of Winter, TV: The Daleks' Master Plan) Sara, (TV: The Daleks' Master Plan) Polly (TV: The Power of the Daleks) and Nyssa (AUDIO: The Mutant Phase, Renaissance of the Daleks, Plague of the Daleks, Dalek Soul, The Elite) have all previously encountered the Daleks.
 * The Sontarans have records of all the Doctor's incarnations. They recognise the Fifth Doctor from their encounter with him on Samur. (AUDIO: Heroes of Sontar)
 * The Doctor initially believes that he and his former companions are trapped in an artificial construct which has been created by the Master. (TV: The Five Doctors)
 * Nyssa would later encounter the Fifth Doctor in her mind shortly before his regeneration into the Sixth Doctor. (AUDIO: Winter) Later still in her personal timeline, she would meet the Fourth Doctor in 3488 (PROSE: Asylum) and subsequently rejoin the Fifth Doctor as one of his companions. (AUDIO: Cobwebs) From the Doctor's perspective, the latter two events have already happened.
 * This is the Doctor's first encounter with each of his first incarnation's companions since they left the TARDIS. (TV: The Chase, The Daleks' Master Plan, The Savages, The Faceless Ones) None of them know that the Doctor is a Time Lord nor are they familiar with the concept of regeneration. Even Polly, who witnessed the Doctor's regeneration into his second incarnation, remains uncertain of the process. (TV: The Tenth Planet) With reference to Ian Chesterton, this will be contradicted in COMIC: Hunters of the Burning Stone, where the Eleventh Doctor meets a younger version of the science teacher and attends his wedding.
 * Polly claims sarcastically that making coffee was usually her main contribution to the proceedings. (TV: The Tenth Planet, The Moonbase, AUDIO: The Selachian Gambit)
 * The Doctor refers to Polly challenging the Cyber-Leader Krail in the Snowcap in December 1986 (TV: The Tenth Planet) and destroying a squadron of Cybermen on the Moonbase in 2070 (TV: The Moonbase).
 * Commander Skaal refers to the Sontaran invasion of Gallifrey. (TV: The Invasion of Time)
 * The fact that Ian is an elderly man would seem to disprove the rumour, as related by Sarah Jane to her friends Clyde Langer and Rani Chandra in 2010, that he and Barbara have not aged since the 1960s. (TV: Death of the Doctor)
