Looking for some thoughts/advice here: Is it important to maintain continuity in writing style over the course of a series? I've already written the first two books of my fantasy trilogy. The first one was pretty strictly chronological. I fudged things a bit on the second and opened with a scene in the future and went back and wrote up to that moment--so except for that opening hook, it was still chronological. I'm now getting ready to write the third, and I'm debating whether or not to allow myself to break the chronology a bit. I want to be able to go back and explore scenes that happened in the past (mostly in the intervening years between book 2 and 3), but I'm concerned that changing the style to include such 'flashbacks' would be disruptive to the trilogy. Is that the mistake of an immature writer or a new element to keep the series fresh? Thoughts?
