How long is too long?
I thought I'd run this question by the community, especially for the writers who have been at their serials for a while and for the readers who have been following stories that have been going on a few years:
I'll be finishing up my fourth book online early May with plans to resume with book five online at the end of August. I'm trying to space out my serial with built in breaks to write other projects and avoid getting burned out, but I don't want to wait too long and lose readers. Is four months an acceptable waiting period between arcs?
I made the mistake of waiting almost a year and a half between ending my third book and starting my fourth due to editing and just life stuff in general and I lost a lot of my original readers waiting that long to resume.
So again, how long is too long to wait?
