Cold Fusion (novel)

Cold Fusion was the twenty-ninth novel in the Virgin Missing Adventures series.

Publisher's summary
'The entire universe is at stake and I'm locked in here with another incarnation of myself, and not even one of the good ones!'

More than one TARDIS lands on a barren ice world. The Fifth Doctor, Adric, Nyssa and Tegan find a once ordered society on the verge of collapse, as rebels wage a dirty war with Scientifica, the ruling elite. All that stands between order and anarchy is the massed presence of an Adjudicator peacekeeping force.

But is peace the only reason for the Adjudicator garrison? What exactly has been discovered deep below the planet's surface? Who are the mysterious Ferutu? And why is telling a ghost story a criminal offence?

The Fifth Doctor sides with the cause of justice and fairness as always. But, as a threat to the universe unfolds, he finds himself in conflict with his past... and his future.

Continuity

 * "Lightspeed overdrive" is first mentioned in DW: Logopolis.
 * PDA: The Infinity Doctors reveals who Patience is.
 * NA: Cat's Cradle: Time's Crucible and NA: Lungbarrow both gave some idea of the time from which Patience is from.
 * This story begins a series of story arcs known as the "Psi Powers" arc for the Seventh Doctor, continuing in NA: The Death of Art and ending in NA: Sleepy.
 * The Fifth Doctor is still recovering from the effects of his recent regeneration. (DW: Logopolis, DW: Castrovalva)
 * The Fifth and Seventh Doctors use a technique which they describe as being "beyond the science of the Humanian Era", namely reversing the polarity of the neutron flow. (DW: The Sea Devils, DW: The Five Doctors)
 * The Seventh Doctor remembers the events of the novel from the perspective of the Fifth Doctor and uses this knowledge against his younger self. This is similar to CC: Peri and the Piscon Paradox, BFA: The Four Doctors and DW: Time Crash in which the Sixth, Eighth and Tenth Doctors respectively likewise remember the events portrayed from the point of view of their fifth incarnation.
 * The Seventh Doctor describes his fifth incarnation as being "bland" and "not even one of the good ones." This reflects the Sixth Doctor's low opinion of his immediate predecessor immediately after his regeneration. (DW: The Twin Dilemma) Conversely, by the time of his tenth incarnation, the Doctor expressed a fondness for his time as the Fifth Doctor. He looked upon his fifth incarnation as a turning point in his life. According to the Tenth Doctor, it was during his fifth incarnation he truly began to enjoy himself. (DW: Time Crash)
 * The Fifth and Seventh Doctors would later meet each other again in BFA: The Sirens of Time and prior to the events of BFA: The Veiled Leopard. The latter encounter is not actually depicted but is witnessed by the former's companions Peri Brown and Erimem. Peri describes the Seventh Doctor as being "a kooky little guy in a weird pullover." She would later meet him more formally in NA: Bad Therapy.
