Abnett starts his foreword with the idea that every Whovian has their Doctor that first introduced them to the show. A true fact, since there is always one Doctor that most fans feel a particular affinity to--and their first Doctor always holds a special place in their heart, even if it's not their favorite Doctor.
Abnett certainly nailed the chemistry that made Eleven and the Pond's so beloved by fans--their banter was effortless, and totally sounded like Matt Smith's Doctor. A mark of great writing when the reader can hear the actors in their head as they read and it sounds truly authentic.
As always, this plot finds the Doctor and the Ponds slightly very far from their intended destinations--Leadworth, to be home in time for Christmas. Instead we find our heroes on a planet being terraformed by people who have been displaced by the expansion of our sun, thus destroying Earth. Unfortunately, the destruction of our planet means the destruction of other lifeforms homes in our solar system, bringing us our foes for this novel--Ice Warriors from Mars.
POSSIBLE SPOILERS AHEAD--proceed with caution!
The Morphans, 27th generation removed Earthlings, unknowingly find themselves the victims of the Ice Warriors hijacking their terraformers. Of course the Doctor quickly sniffs out that there is something amiss and stumbles his way into solving the problem. After the Doctor is captured by the Ice Warriors, and embarrasses himself by showing off his credentials with the Martians (before his credentials have been established in their history), he hatches a plan to save the Morphans's home, dubbed Hereafter, and still find the Ice Warriors a suitable home in the solar system. I won't divulge the Morphan/Ice Warrior common enemy, that is an interesting twist for each reader to discover on their own, but the story was enticing and exciting, and all around a fun read for fans of the Eleventh Doctor.
