My plan of reverse engineering my timeline worked out pretty well.
I went old school first, printed my outline from Scrivener, taped it together, and figured it all out. Moved a dozen scenes around and identified a dozen new scenes I have to write.
Next step was to organize the Binder (in Scrivener) by days. I made still more changes during that process. Mostly for pacing and continuity.
The novel spans 15 days. Part One (~38K words) is one day. A lot happens. The pace picks up considerably after that.
Having (mostly) solved this time issue, my next problem is with “backstory time.” I’m constantly referencing where Odin’s been for X years, and a war that happened Y years prior, along with other events that happen still farther back.
Right now I just have placeholder timespans in there, but I need to figure it out. In time.
