My Unborn Baby Called Me Out

In the world of a novel, Rosie Grant's mother is a woman blinded by love and her father is a freeloader after the family money, and the family is headed for ruin. Rosie died saving the world and woke up as a fetus inside that book. She panicked, and then her thoughts started coming out loud enough for her mother to hear. Her mother heard them and came out of her infatuation. Working from what Rosie knew, her mother's side of the family closed ranks, outmaneuvered the father and got rid of the mistress. By the time Rosie was born she and her mother were the most doted-on members of the Grant family.
