Many authors and artists quit their jobs cuz they weren't getting paid. Our author who wrote this series went to a different company and tried to continue the series but the previous company pulled a copyright lawsuit for the rights of Black Haze. The author tried to fight against it, but eventually posted on their blog that it was looking very unlikely that they'd be able to continue the series and to consider the latest chaper to be the last, seeing as it would be very slim chance of the series continuing any time soon.
