Her Lies Shattered Me, My Return Will Break Her

Flora Belle was a physicist with a career ahead of her when her adopted sister killed someone. The family asked Flora to take the blame to keep the name clean, and she did. Five years later she comes out to a house that has moved on without her. Her parents are cold to her. Her sister has taken up with Henry Woods, the man Flora loved, and Henry believes the version of events he was given. Flora stops arguing about any of it and goes back to physics research, which is the one area where nobody can rewrite her results. The old story starts coming apart anyway. Years before, someone pulled Henry out of an accident and he had always believed it was the sister. It was Flora. The sister had built her whole standing in the family on things that were not hers, and one by one the incidents she staged and the injuries she caused come to light. Henry works out what he chose and what it cost, and by then Flora is no longer offering to absorb anything on anyone's behalf.
