This is the sixty third release from Big Finish in their range of full cast audio adventures starring classic Doctor Whos. It stars Paul McGann as Eight, India Fisher as Charley and Conrad Westmaas as C'Rizz. This is the seventh of a series of adventures in the Divergent universe following the events of Zagreus, in which there is a story arc. Knowledge of some of these previous adventures will help with the enjoyment of this as it starts to bring the divergent saga to a close and explain a few things. There are 4 episodes, roughly 25-30 minutes each, complete with original theme music between each, and cliff hanger endings. Two episodes per disc on 2 discs, and a short booklet with some pictures of the cast and production notes.
After a series of adventures being passed from zone to zone by the Kro'ka, the Doctor is finally starting to get a handle on what is going on, and begins his fight back. This results in him, Charie and C'rizz being transported to the Caerdrioa zone, where things start to get very weird. An interesting series of adventures follows, as the Doctor works his way through the oddness to find what lies at the heart of the zone. It's one of the better adventures in the divergent saga, with some interesting ideas, a good sense of humour and a good use of the audio medium to present us with monsters that simply could not be realised on the screen. There is also some great acting, especially from McGann who is called upon to do some very tricky work showing three aspects of the Doctor at the same time and doing it superbly - it's just his voice, but you can hear three separate characters.
An excellent production all round, 5 stars.
