At the end of the televised story The Massacre, Dodo wanders into the TARDIS while it is parked briefly on Wimbledon Common in 1966; by the start of the next story, The Ark, she is perfectly happy to believe that the TARDIS has taken them to a different part of contemporary England, but has difficulty grasping the possibility of time travel. Also (to the mockery of generations of fans) her accept has completely changed, from something rather north of England to something more uncertainly southern. Salvation rewrites Dodo's first scenes in the TARDIS as part of an encounter with godlike aliens in 1966, which takes her, the Doctor and Steven to New York. Lyons has invented vast amounts of back-story for Dodo here, all of which makes the character (and her accent quirks) much more believable; he does the same to a lesser extent for Steven, catching Peter Purves' characterisation of him perfectly while also adding to his background. And his Doctor is very Doctor-ish, taking charge of the confused officials trying to deal with the situation, confronting and defeating the bad guys while also determined to minimise casualties. The exploration of humanity's relationship with gods, and with belief, is a bit pale compared with Neil Gaiman, but then isn't everything? My biggest criticism is that while Lyons gets New York's physical geography, he does not really capture the city's vibrant multi-ethnicity very well; most of the American characters might as well have been English, which is a bit ironic given that he saves the phenomenon of Dodo's accent.
