FreeMind

Here's my first go at the mind map, made with FreeMind. (Click the image to view a clearer version)

Each node is a story title and each subnode is the name of each character in the story.

The next stop is to link each at least one character with another in a different story. As I was thinking of blood linkage I might create a mind map of a large family along with spouses/partners.

The software is free to download and is easy to use.

(P.S. Can you work out the theme of the novel from the story titles?)
