So what did happen to Queen Susan?

I've read a little fan fiction in the past. I discovered it was largely REALLY bad and haven't bothered since.

Until I saw this:

A story of happened to Queen Susan after
The Last Battle

Perhaps not the best writing, but actually a satisfying ending for Susan.

Amazon Sillyness

So what do you make of this book listing on Amazon?

1) A REALLY old but seminal work
2) A good deal on an antique book
3) Human error
4) Computer error
5) Amazon not paying attention to lower selling stuff
