My WIP stalled when I realized it was going to top out at 20K words, too short for a novel. So I went back and reworked my plan for it. It's a mystery in which a first-year law student finds out the truth about her dead parents, who died when she was a baby. I wrote a two-paragraph summary of the novel, then a description of what really happened and she'd been lied to about, then a list of the facts she'd have to uncover. Next step will be to list what evidence of each of those facts would survive for 23 years. After that, I start shuffling the evidence around until I find an order that makes sense for her to discover them in. The problem is that, even combining some things that would naturally be combined, I have 59 facts for her to find. I expect there to be more than 100 pieces of evidence. I'm crapping bricks about that because the novel could end up being far too complex for readers to enjoy--and perhaps for me to write. Any suggestions?
