I’m going to mention here, since it’s off topic for the original thread.
The free sample ended up as “volume 1” of the series, with “volume 2” being the full version. That seems pretty confusing
Maybe longer free samples should be handled separately? Back when I only read one for a different book, I just marked my status as “stopped” but I guess it might not be satisfying for some. Maybe it should be a specific entry on the book page?
