After what has been a stretch of quite boring and run-of-the-mill stories, it's nice to get to one that is just really very good fun, it isn't the deepest of mysteries, but what it sets out to do it achieves quite well. It uses the setting of the divergent universe and The Kro'Ka much better than most other stories set in this universe and it is quite cathartic to see The Doctors and co. finally coming face to face with them.
All together: won't set the world on fire, but was quite an enjoyable listen the whole way through.

8/10
