many feelings
Format: Kindle
I didn’t know what this book was about when I first started reading.. one thing I felt at the beginning was…amazement? I love writing letters, something I don’t do often, I recently bought this beautiful fountain pen, I wanted to start small, writing greeting cards to family and friends, birthday cards, thank yous, etc. what I didn’t expect is the emotional toll this book had on me, and other members of my family who read the book for our book club. The subject matters, death of a child, husband dying of cancer, the significance of May 29th, all impacted our family, and so, as I read this book, I had to put it down several times because I had to cry, compose myself, think of regrets I have, and remember.
How amazing it is that Sybil was able to write all about the death of her child to her dead child. I always say that writing it down on paper releases your burden in your head…it is true, I think writing letters, even the ones she didn’t send helped her quiet her head, at least for a while. I truly love this book. I have been borrowing books from Libby to read for our book club for a very long time, there have been books that I fell in love with, and always thought if I want to read them again I’ll just borrow them again, this book is the first one that I want to own physically to put on my shelf and know that I have it to read over and over again when I want to reflect and then quiet my head. ( This is the longest review I’ve written about a book I’ve read, I hope it makes sense).

Successful Epistolary Novel
Format: Kindle
When we first meet Sybil Van Antwerp, age 73, she is retired from law and spends a lot of time writing letters and emails. She also reads a lot and is interested in what her correspondents are reading. She has children and grandchildren, but she lives alone in Annapolis, Maryland, and doesn’t see her family very often. During the course of reading her correspondence, we very gradually learn about Sybil—her history and her present troubles. She is a complicated character and several times in reading The Correspondent I paused to ask myself what I thought of Sybil—did I like her? What about her kept me from the immediate response a reader usually has about the main character of a book? Even at the end of the book, I am still ambivalent about Sybil, but I certainly understand her much better.
Sybil, herself, and the book have so many layers. There is true depth to the story. My book club took deep dives into it over a period of three weeks, and I don’t think we have sampled all the topics represented in this book. It is a wonderful novel for stimulating meaningful discussion.
Neurodivergence is not called out or named, but it comes to mind in thinking about Harry, a child who is the son of a judge, a former colleague of Sybil. The boy doesn’t quite fit in socially with his peers, but he is brilliant. Sybil makes the perfect “pen pal” for Harry because they have some of the same characteristics. As a child she was punished for “insolence and rudeness,” but her parents were just trying to mold her into a polite young lady as expected by society. She was blunt and didn’t have many friends.
There are so many other issues worthy of discussion, but they would most certainly bring up spoilers. I won’t do that to you. Readers should have the opportunity to see the story gradually emerge from the letters, including a continuing one that the reader doesn’t know to whom Sybil is writing. Sybil sets the word “stone” for secrets, and there are stones in this book making it a puzzle, a mystery of sorts—for the reader.
As a reviewer, I tend to go quickly from one book to the next as soon as I have composed and published my thoughts. Characters in various books can even blend together. This is not the case with The Correspondent. The characters in this book, especially Sybil, have stayed with me and come to mind frequently as I go through my day. Virginia Evans has created a fictional world with impact. Just as Sybil needed time (years in her case) to process the events of her life, the reader will need time to process them and their effects on Sybil as well.
