Leah and Diane are sisters and have always been close. With no other family they have always been there for each other. Diane is married to Paul and has cute twin boys. When she finds out she is pregnant her husband and her are elated. After the birth of their 3rd child Diane dies after childbirth. Diane convinced her sister would have done anything if their situations were reversed she does everything to help Paul and his three children. After 6 months after Diane's death she decides she should move in with Paul to help him more. So from there it is predictable what will happen by the end. I enjoyed the story and was slightly weirded by the whole thing as well.
