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.

Love this book!!
I just finished *The Let Them Theory* by Mel Robbins, and I can honestly say it completely shifted my mindset. The concept is so simple—“let them”—but it’s incredibly powerful. Instead of stressing over what other people think, say, or do, this book teaches you to let go of that control and focus on yourself instead.
What I loved most is how practical it is. It’s not full of complicated advice—it’s something you can actually apply in real life, whether it’s relationships, friendships, or everyday stress. I found myself reflecting on so many situations where I was wasting energy trying to control things I simply can’t.
Since reading it, I feel lighter, less anxious, and more in control of my own life. It’s honestly a reminder that peace comes from within, not from trying to manage everyone else.
If you’re someone who overthinks, people-pleases, or struggles with letting go, I highly recommend this book. It’s simple, but it hits deep.

Four Stars: Insightful and Impactful Reading
Format: Hardcover
This book provides clarity in human relationships pertaining to workplace, family, and social circles. Author Mel Robbins explains the human tendency of needing to belong and bond, having personal freedoms and space to make informed choices, and providing coping strength to not feel over burdened due to work or perceived social obligations or human stereotypes. "Let Them", "Let Me" is a series of strategies/skills that help one regain focus on finite time and energies to have more productive personal relationships and work outcomes. The book teaches one to de-prioritize things and channel emotions into actionable goals to set healthy boundaries in selection of friends, career paths, and effectively resolving conflicts. Some chapters are overly redundant (and precludes a fifth star rating); however, it's a worthwhile book that definitively helps me set more impactful goals in 2026 and beyond.
