This story is easily one of the greatest ever Big Finish audios. It acts as a direct sequel to The Metaphysical Engine, Or What Quill Did, and it's tons of fun from beginning to end.

Blair Mowat's script gives us such wildly different takes on the Class characters, as they play alternate universe versions of themselves. Tanya as the Queen of Rhodia is a particular standout, giving us a glimpse at a more ruthless take of the character.
