It's not a mind-blowing story but it is a lovely surprising, adding texture to the world we'll soon get to see. Doctor Who prose often feels divorced from other media. Sometimes that's to its strength (the 8th Doctor books have some real fun going their own direction), but it would be nice to see more crossover like we have here. Especially with the abbreviated seasons we have these days, which don't give us time for two-parters. Prequel, sequel, or addendum stories could really serve to flesh out what we get on screen.
