I can't remember the title of this book, please help me. It was a few years ago I read this so not that recent.
A young women witnesses a car accident and stays with a woman in the car while she dies.
She then starts to spend time with the family and the husband think they had teenage children and were wealthy. She develops feelings for the widowed husband and infiltrates their life. She then embellishes last words from the dying wife and tells the children this.
Thank you!
