The story takes place before the Doctor took on any companions, and just had his granddaughter, Susan. It happens in Victorian London. The story itself is very brief. The only reason it took me so long to read it was that I had too many things going on to read for more than a few minutes at a time. It's okay. I like some of the concepts in it, like the pirates, and it would be cool to see them again somewhere, maybe in a longer novel or an episode. It wasn't bad as some of the other reviewers found it. I just felt that there should have been more to the whole thing.
I do recommend the story for fans. Maybe as a bedtime story for themselves.
