What I Did on My Christmas Holidays by Sally Sparrow (short story)

Summary
to be added

Characters

 * Ninth Doctor
 * Sally Sparrow

Continuity

 * As this story was later remade for television, it is difficult to place it as happening within the established "canon" unless it takes place in an alternate universe. If an attempt is made, it likely takes place before the Ninth Doctor meets Rose Tyler, as he is without companion. (In fact this is one of if not the only officially licensed Ninth Doctor story in which the Doctor is not depicted as travelling with Rose.)
