I think focus is good no matter what sort of publishing your doing. It takes time to build a following e-pubbing but I know that complete series help.

I am forcing myself to stay on track with Tx3. If I do nothing else that will be done. I have plans for it to be a series if anyone wants more. But I do maintain a stable of side projects. BUT I make sure the side projects are stand alones.

I am excited to to see the results of a new cover too!
