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.

exceptional, very highly recommended character-driven literary family drama
Format: Kindle
Whistler by Ann Patchett is an exceptional, very highly recommended character-driven literary family drama which will definitely be one of the best books I've read this year. In Whistler Patchett has given us a beautifully written, eloquent, insightful and sensitive story encompassing the complexity of families, connections, and relationships over time. I love everything about this book. As they were visiting the Metropolitan Museum of Art, Daphne Fuller's retired husband Jonathan notices an older man following them and they discover he is Eddie Triplett, Daphne's former stepfather. She hasn't seen him for 44 years but immediately remembers her love for him and the bond they had for a couple years. The two also shared a traumatic experience when she was nine and they were in a car accident. Immediately after this Daphne's mother divorced Eddie and he disappeared from her life. After this chance meeting and reconnection, Daphne immediately and understandably needs to see and tell her younger sister, Leda, about it. The sisters had a complicated childhood that Daphne never felt was very happy. Daphne and Leda's biological father, Buddy Zabriskie, was a deep-sea fisherman and left the family early, although the girls had a relationship with him. Then their mother married Eddie and both girls loved him for the brief time he was in their lives. Their third and final stepfather, Lucas Ekker, still lives with her mother in Massachusetts and they had two sons. The two sisters were done with stepfathers at this point. As the narrative unfolds, Daphne and Eddie continue to meet and restore their relationship as father and daughter, but now as adults. While following the present day events, Interstitial chapters jump back in time when Eddie was her stepfather and cover the events from when they were in the car accident. It is during these interludes back in time that were learn the story of Whistler and also see the deep connection between Eddie and Daphne. Events in both the past and present show how complicated interpersonal relationships are, how little we truly understand of our past, and, ultimately, how fragile life can be. Because this is a character-driven story, all the characters are portrayed as realistic, fully realized individuals with strengths and weaknesses. The narrative examines relationships, choices made in both the past and present and how many seemingly small and inconsequential moments can follow us our whole lives. It also gently shows how being recognized and understood by another person, even for a short period of time, can change your life and theirs. Whistler by Ann Patchett is a wonderful choice for everyone who enjoys thoughtful, sensitive, character-driven literary novels. Thanks to HarperCollins for providing me with an advance reader's copy via Edelweiss. My review is voluntary and expresses my honest opinion.
