A 'trilogy' or...
I have written a new book which I'm calling The Third Rule. When I finished it, it was almost 300k words long. Much too long for one single book; so I decided I would split it into three volumes.
The problem I have is that to call it a trilogy might imply it was three separate stories wrapped around a central premise, theme or character, which it isn't. I don't want to mislead people into thinking it's three separate stories.
It's the word - or the use of the word - 'trilogy' which is causing me problems. So how would you describe the collection of all three books since I'm a little wary of calling it a trilogy?
And as individual books, should I describe them as The Third Rule, Part One... or, The Third Rule, Book One... or what do you suggest?
Thanks for your help.
