I wrote out a long post, and I just deleted it. Here's my simplified question: at what point does a story with multiple plots become overwhelming? Right now I have three: I have a main story frame with its own plot, and then two other plot lines that occur in different times and places, but matter greatly to the MC's plot line in the main story frame. I'm trying to weave in and out of them, and tell the two other subplot stories concurrently (one chapter for one character, another chapter for the other, etc). I have a good device that brings me back and forth very easily, but I'm worried it's going to be too confusing advancing the two "internal" plot lines at the same time. Or am I overthinking this.
