I have an idea for a fantasy book series I want to write that follows the life of a particular character from childhood and on through adulthood as she follows the route of a basically good person who turns to evil and then goes back to good and seeks to redeem herself and make-up for what she's done. I was having trouble coming up with ideas for stories in her early life but then my boyfriend gave me the idea of starting the first book with as a teenager when she gets captured by slavers(since this is the next part after the death of her parents when she was 5 that has the most development and the most for me to go off of. Starting it there I could have the story of how she escapes from servitude and have the whole dilemna of whether or not she should return to her people or remain with the wizard who has been training her since her parents died. However I could also interject scenes from her childhood and adolescence throughout the first 1/3-1/2 of the book to reveal backstory, where she comes from, and how she wound up where she is, as well as revealing the kind of relationship she has with the wizard I mentioned. I was wondering if anyone here might have any tips on how to write a story that delves a lot into a character's past or even if it's a good idea to write a story like this. Are there any books out there that have a lot of flashbacks or backstory in them that I could read to give me an idea of how to go about it? Any advice or help would be much appreciated. Thanks.
