The Correspondent by Virginia Evan

Every morning, Sybil Van Antwerp sits down to write letters – to her brother, to her best friend, to the president of the university who will not allow her to attend a class she desperately wants to take, to her favourite authors to tell them what she thinks of their latest books, and to one person to whom she writes often yet never sends the letter. Because at seventy-three, Sybil has used her correspondence – witty and wise – to make sense of the world.
But beyond the page, she has spent the last thirty years keeping the people who love her at arms’ length... Until letters from someone in her past force her to examine one of the most painful periods of her life. Now, Sybil must send the letter she has been writing for all these years - and find forgiveness within herself in order to move on.
