One ought to be familiar with Jack a bit before tackling this.

If you are, it is a pleasant enough romp with Jack, as advertised, in the Victorian Age, on the path to joining Torchwood. I enjoyed the queen here and little moments in their adventure travelling around. Some of the plot was a little silly, but it is easy to forgive thanks to what felt like a pretty laid-back tone to this audio. Not terrible, not great, but fun enough and pretty well performed.
