Having trouble with a plot... A character in a fantasy/sci-fi setting has lived here on Earth for about 1200 years. Events happening "now" are linked with her childhood--1200 years ago. I can't decide whether to leave her memory intact and do flashbacks or add in the tension of not being able to remember except in bits and pieces. I would use the "memory faded with time" approach, except that she's a member of a race that doesn't have those problems (yay for genetic enhancement), so it's either "flashbacks" or "cleverly-devised reason for not remembering anything except the past 30 years or so". Thoughts? Preferences?
