It is the first BBC Books novel to feature the death of a companion, although the death is retroactively prevented through the use of a temporal orbit by the Doctor.
Publisher's summary Edit
The planets Janus Prime and Menda are diametrically opposed in orbit around a vast Red Giant star. But while Menda is rich and fertile in the light of the sun, Janus Prime endures everlasting night, its moon causing a permanent solar eclipse.
When the Doctor and Sam arrive on Janus Prime, they find themselves in the middle of a war between rival humans colonising the area. The planet is littered with ancient ruins, and the Mendans are using a mysterious hyperspatial link left behind by the planet's former inhabitants. But what is its true purpose?
The Doctor and Sam must piece together a centuries-old puzzle. How can Janus Prime's moon weigh billions of tons more than it should? Why is the planet riddled with deadly radiation? As the violence escalates around them, will the time travellers survive to discover the answers?

- Sam gets extreme radiation poisoning and then dies of Janusian radiation poisoning at 019.04 Mendan time. However she is (retroactively) saved via a temporal orbit and the Doctor developing a cure.
- Gustav Zemler has already gone quite mad from radiation poisoning. Because of said radiation poisoning, he can access the Janusians' alpha waves and communicate (after a fashion) with them.
- Moslei was born in 2162.
- The Doctor and Sam meant to be heading for Earth, Egypt, 1871 for the inaugural performance at Cairo Opera House.

Theories and concepts Edit
- Korman radiation scale is a measurement scale used aboard the TARDIS.
- Alpha waves are somewhere close to telepathy.
- The Doctor "parks" the TARDIS in a temporal orbit to spend time working on a cure for the Janusian radiation sickness.
- Sam is shot at; her shoulder gets glanced by a laser rifle and gets infected.
- The "Korman radiation scale" is most likely named after Kate Orman.
- Sam knows there's a cubbyhole above the "P" of the TARDIS outside Police Box. TV: Doctor Who.
- The concept of a "temporal orbit" first appeared in TV: Doctor Who.
- The Doctor isn't afraid of spiders despite the whole Metebelis 3 thing in TV: Planet of the Spiders, which is odd because in PROSE: The Scarlet Empress he said he was afraid of spiders.
- Sam visited Skaro in PROSE: War of the Daleks, Hirath in PROSE: Longest Day and the Dreamstone Moon in PROSE: Dreamstone Moon.
- The Doctor and Sam saw similar space/hyperspace warping in PROSE: Vanderdeken's Children.
- The Doctor plays with his train set whilst the effects of the Janusian Radbuster take effect in his body. (PROSE: Model Train Set)
- Sam claims she has never heard the Doctor's real name, despite being told it in PROSE: Vanderdeken's Children.
- The Tenth Doctor will recall Thurakzima 7. (COMIC: Signs of Life)
