One of the problems I've been struggling with as I write and revise Jane's Air is either sharing Too Much Info (TMI) or Not Enough Info (NEI) (Okay, I just made NEI up. Maybe if I start using in in texts it will catch on).
For example, my antagonist, Isaac Strickland, has a very dark past. I know it's important for the reader to know about it, so they understand his motives, but at the same time I'd rather not include all of it.
Then there's the whole background info and physical characteristics thing... I try to avoid info dump, but at the same time it gets hard to fit everything in.
How do you guys find middle ground between TMI and NEI?
