How do you decide when it’s time to move on from a series?

At the moment, I have three volumes in my Jasper, Amazon parrot series, with the fourth one about to be published. I have my Squirrel Mafia series. One is out, while the second is about to be released.

I have many manuscripts to work on, which I know is a thing with writers. Something else in common is having a notebook of ideas to work on. The list will be long, and we will not get to them all.

It is those projects I want to work on.

I need to decide if there is more material I can expand with the series I have out. I already have a list of ideas for ten chapters for a third volume of my Squirrel Mafia series. But I need to decide if people also are interested in reading a third one.

For Jasper, I have received many great reviews and feedback from parents, teachers, and children who have read the book themselves. Do I have material for a fifth book? I am not sure. The series talks about problems with the rainforest. I need to develop a story around one if I can come up with something. For this series, that is what it comes down to.

I have discussed this topic on this site before. Apparently, I am uncertain where it lies.

Hopefully, soon, the answer will come to me.

Until then, I will continue to write.
