Every Woman Has a Price is going to have a large cast. There needs to be at least 25 characters: Owen, 12 bodies purchased, and 12 enemies accidentally scooped up. In addition there's Grandpa, Kirk, and Maxim. With a cast this size and the delay between postings I usually include a cast list. I haven't, yet.
Should I post the whole list now or update as characters are named and appear? If you read the story what do you think? Include the cast list or let the readers remember? Have the whole thing available from the start (it'll be the first chapter-link either way) or add names to it as they occur. Once the story is finished there'll be a brick of potential spoilers right at the start anyways.
If you include cast lists in your stories, I'm interested to know how you approach it as well.
Anyway, go read https://storiesonline.net/s/20106/every-woman-has-a-price it's going to be one of my best.
