I created a couple of mindmaps on the website bubble.us, which was an excellent online tool. It was a very quick and easy way to jot down ideas while keeping them in an orderly fashion.
I created one for the two main characters in the book, which are Gonzo and Ruby. They both have very different traits that are evident in the mindmaps.
However, from completing them, I realized that the two characters also share aspects of their personality that connects them such as loyalty and affection.
