This is part of a series of reviews of Doctor Who in chronological timeline order.

Previous Story: The Labyrinth of Buda Castle

An absolutely genius story, this two-parter might be one of the best things Big Finish has put out. It's such a simple but totally unique concept. A planet at war with it's own ancestors. This story is absolutely fascinating and the way the Doctor and Romana keep ending up on both sides of the conflict, with their actions influencing both the past and the future is brilliant to hear play out. I love that K9 gets such an active role in the story.

Genuinely an incredible story.
