To be honest Bethania, you can do pretty great organization with google drive using well arranged folders, documents, and bulleted or numbered lists. If you want some sort of timeline tool for events, something like Sutori could be useful. Now, it becomes more and more useful to have a special tool (like Scrivener) the bigger the book or series you are writing. So if you’re writing a epic fantasy series, then you might want a better tool. Scrivener is the tool of heard the most good things about, and I’m sure I’ll try it out some day. What is your WIP’s plot and setting btw?
