Let's launch the Randomoid Selectortron away from the forgettable Vienna and see where it goes next...
Doctor Who: Dust Breeding
Starring: Sylvester McCoy as the seventh Doctor and Sophie Aldred as Ace
Format: Two full-cast CDs (or download) of four half-CD episodes
Silly? One element of the premise is silly but it's not an important element and isn't dwelled on extensively.
Standalone? This is an indirect sequel to events in the novel Storm Harvest. The aliens from that novel appear here without being given a detailed description.
Recommended? Yes due to its low price and the Big Finish debut of a significant actor.
My reactions to this story contain spoilers for it, other Big Finish releases featuring the same villain, other Big Finish releases featuring the character of Bev Terrant, and The Fearmonger.
