Both of mine are under 15. Here's a bunch of short stories that differ in style, character perspective and theme, yet are actually connected (or will be through future stories) - Currently sitting at 7 subscribers/16 episodes (started in September this year)
And here's a sci-fi novel following a morally ambiguous mercenary with a knack for getting herself and others into trouble - Currently sitting at 4 subscribers/2 episodes (started last week)
I'm open to feedback so I can push the quality (and subscriber amount) up.
