Chronologically, the story begins with the protagonist as a child and description of her world, which is important to the plot.
Since I thought "girl abandoned by parents meets a man who explains how the world works" wouldn't really catch the readers attention, I decided to start the book with a 4k long flash-forward to a fight with elements relevant to the main plot (titled Prologue: A battle to come, to signal future events).
After these two Chapters I get to the main story (from her teens), with a few flashbacks here and there written in first person (the part about the description of the world is also in first person).
Does this make any sense or is it too complicated? I really don't want to have a somewhat boring beginning, which is why I avoided beginning with her childhood...
Thank you and sorry if there are mistakes, I'm not a native speaker.
