Recently I decided to embark upon a return journey through the Eighth Doctor Adventures published by BBC Books during that horrible period of time when there was no Doctor Who on television, and the only way that we could experience The Doctor's adventures was through (to many) the non-canonical novels and audio dramas. I decided to start this journey with Lawrence Miles' Alien Bodies (mostly because I am a not so closet fan of his Faction Paradox concept). The parallels between this novel and the season finale are interesting (and I am pretty sure coincidental).
I should warn that there might be spoilers in this, but I think that spoilers have a statute of limitations...and 16 years is more than enough time for everyone to catch up on the book. If you don't want to see any spoilers of the novel, don't go past the jump.
