To continue or start fresh?

As I start the final book in the Second Chances Series, I am pondering where to go from here. While I enjoy having all of my characters connected, I wonder if it's time to start fresh with new faces in a new place.

I enjoy letting you see the marriages and births and engagements spawned from previous novels, but I worry that it may get old. Alas, there is still plenty of time to make a decision. I'm only a few chapters in to the current book and only have plans for a companion novella for the Finding Harmony Series after that.

Who knows what may pop into my brain after that.....
