Hello, I am trying to find a book title, i have been googling without finding it and it is frustrating. What i remember of the plot is this : the female character is asked by the mother of an old school 'friend' to see her , maybe to help her, what the mother doesn't know is that the female character was one of the bully who made her daughter's life hell. I remember that the female character is very reluctant at first (of course without being truthful to the mother why), but then find herself agreeing, and then revisiting the truth of what happened at school, and feeling the guilt and remorse. If anyone could help me i would be very grateful. thank you, this book dates from only a few years back.
