Software for plot building across multiple books
I plan to write a series of books set in the same universe, with a major plot about war, destruction, murder, killing, love, betrayal etc.
But I am having problem getting the big view of my universe plot and each separate book plot. Does any one of you know of a program, tool, anything that can help me get a better picture of the plot as I write the different books?
Most of programs for writers I have seen have only the option for one plotline - the one the specific book is about - but I need one where I can put in the major plotlines and what happens in the universe and then put in each separate bookplot.
Does anybody have an idea for a nice tool or program to use?
