Invisible Threads

by MAUREEN WALGREN

What began as an ordinary January day in 2017 became every parent's worst nightmare when Maureen and Doug Walgren's sixteen-year-old son, Corey, died under shocking and tragic circumstances. Invisible Threads addresses the unanswered questions, rumors, and truths that followed-and the lasting impact on a family and community searching for meaning. 

 

Maureen, Doug, and their two surviving children faced a grief that reshaped everything they knew. As they struggled to endure the unthinkable, they were confronted not only with loss, but with public scrutiny, a malicious internet troll, a serious hospital HIPAA violation, and a two-year legal battle with the local school district and police department-whom they believe literally scared Corey to death during a school disciplinary incident that ended in tragedy. 

 

Covered by national and local media, the case exposed troubling gaps in how schools handle discipline and student vulnerability. The Walgrens found purpose in helping to get a new law passed and in starting a non-profit in Corey's memory.  

 

At its heart, Invisible Threads is a deeply personal memoir about love, resilience, and connection. It is one mother's honest account of grief and healing, and the unexpected ways a life and a loss can continue to connect us, weaving people together in ways both seen and unseen.

This memoir was very interesting and about half way through the book I got up to get a glass of wine and thought to myself, this book is really holding my attention, then I thought...and this is someone's real experience-yikes! Some of it is sad and some of it is happy and even inspiring. I think it's very cool because this family took their tragedy and tried to help others...no...they DID help others by trying to ensure that this doesn't happen again to someone else's son! There are actually schools that are safer because of steps that were taken by this family even when the community was not always supportive about it! I feel like anyone who has lost a child, or if you have a friend who loses a child, the book could really help to navigate and better understand the roller coaster of emotions that happen to a family going through this. Throughout the book, the author did a great job talking about the invisible threads that weave in and out touching countless individuals throughout your life. It makes me think of how small this big world can be sometimes and how you can find help, knowledge, and inspiration through these small interactions with others - if you can get to a place where you can let it in.

This book isn’t a story- it’s a recounting of the most horrible event a parent can experience. Maureen’s ability to put her grief into words is amazing to me. But more than that her ability to share how she is living and growing with her grief is a testament to her character. I appreciate her reminders to us to that not everyone is having a great day and that we should remember and talk about loved ones that have died.

Losing a child is a horror no parent should ever have to experience, and yet, Maureen does so twice; once in real time and again in the retelling in her memoir. This is a testimony to her courage, resilience, and dedication to working through grief and wanting to use these events to help others. This book is a gift to all who read it. It is both heart wrenching and uplifting. The author did not shy away from exposing her raw emotions. Her writing style was engaging to the point that the reader experienced the rollercoaster of emotions that she lived through, not just the day her son died, but for the years that followed. She invited us to walk her journey with her, and although it is personal to her, her grieving process has common threads that can resonate with all of us. The loss that Maureen experienced could have made her more insular but she chose to use it as a way to help vulnerable young adults by putting a spotlight on how schools and the police handle delicate matters. I appreciated that the author was open to seeing signs of her son’s presence after he passed. Finding joy in suffering is a difficult concept to embrace. In the end, Corey’s short life impacted more people than his family could have imagined. Invisible Threads helped make that happen.

Invisible Threads by Maureen Walgren feels deeply personal which allows the reader to feel connected to her in a most profound way. The way she shares her own experience with grief and loss is honest, gentle, and quietly beautiful—it doesn’t try to rush healing or tie everything up neatly. It just sits with the emotions, and that’s what makes it so powerful. It left me feeling reflective and more connected to the people I love. I thought about my own losses and how I may or may not be dealing with grief. It opened my eyes and my heart to living life and experiencing joy after loss.

This book was absolutely excruciating to read at times because of the raw honesty and depth of this mother’s heartfelt experience. Yet, despite the pain woven throughout the story, it ultimately leaves the reader with an overwhelming sense of peace, joy, and hope.

The writing is beautiful and deeply moving, offering lessons for everyone about grief, pain, and the sorrow that can come from another person’s trauma. Most importantly, the book explores how we can emerge from suffering stronger, more connected, and more compassionate. A powerful and unforgettable read.
