To avoid this, write in first person... Well, even in True Blue, though, I have jumped between father and child - and had one planned arc told by a guest character, so this is not a perfect option... And the Jack Diamond books had one planned installment where he's in a coma for most of the story, and Carol and her dad swap narration tasks.
Guess I've only been able to stick with a single character in Strange Awakening.
The non 1p story I've stayed with the MC the most for is Digital Cowboy Dane - only had to "jump away" from him about four times so far, I think the chapters that were posted here had the first of those jumps before I had to take them down.
The story I am the worst with has an ensemble cast - when David West is present in a scene, he gets the POV for Between Earth and Pyrroth, but all of the other main characters, and some of the villains, have gotten their own sections, one that took a few chapters.
