Cold Fusion is an original novel written by Lance Parkin and based on the long-running British science fiction television series Doctor Who.

Also appearing is the Seventh Doctor, with Chris and Roz, from between the Virgin New Adventures novels Return of the Living Dad and The Death of Art.

[10] Empire magazine recommended the book if someone were to only read one Missing Adventure, describing it as "mind-bending sci-fi with the Fifth Doctor (and a cameo for the Seventh) and an inside-out TARDIS.

It starred Peter Davison, Sylvester McCoy, Janet Fielding, Sarah Sutton and Matthew Waterhouse reprising their television roles as the Fifth and Seventh Doctors, Tegan Jovanka, Nyssa and Adric respectively.

In addition, Yasmin Bannerman and Travis Oliver reprised their roles as the Seventh Doctor's companions Roz Forrester and Chris Cwej from Big Finish's adaptations of the New Adventures novels Damaged Goods and Original Sin.
