I have a story in my head about a group of ex-pat women, their relationships, and how they cope with living abroad. Each woman will have different things going on in their lives - newlyweds, happily married, constantly fighting, with kids, without, etc. I will, without a doubt, have at least four main female characters. But can I have one or two more? At which point will it be confusing to the reader, do you think? There will be several other women in the group, but they will just be on the sidelines of the scenes.
