National bestselling author William Elliott Hazelgrove has disclosed new details from his forthcoming book, The Camp Mystic Flood: A Story of Tragedy and Heroism, during a recent interview on WCPT 820 Chicago with host Richard Chew. The book, set for release by Bloomsbury on July 8, 2027, reconstructs the catastrophic July 4, 2025 flood in the Texas Hill Country that claimed the lives of 146 people, including 27 young campers at Camp Mystic.
Drawing on months of on-the-ground research, Hazelgrove provides a comprehensive account that goes beyond assigning blame. The narrative covers the sequence of events from initial weather alerts to desperate rescues, highlighting remarkable acts of courage and the challenging questions that emerged in the aftermath. In the interview, Hazelgrove discussed traveling the Guadalupe River with first responders, walking the flood zone, and interviewing survivors and rescuers. He also examined thousands of pages of investigative reports, emergency communications, and eyewitness accounts.
The book details the minute-by-minute rise of the Guadalupe River before dawn and the final hours inside Camp Mystic as counselors and campers struggled to survive. It also documents extraordinary rescues by Coast Guard helicopter crews, first responders, neighbors, and ordinary Texans, as well as the search that continued long after the floodwaters receded. Perhaps most troubling, the book explores how one of America's worst freshwater disasters unfolded despite modern forecasting technology, prompting legislative investigations, lawsuits, and a lasting impact on Texas summer camps.
Hazelgrove emphasized, “This is not a book about assigning blame. It is the story of what happened, why it happened, and the extraordinary courage shown by so many people in the darkest hours of that morning.” His work is known for narrative nonfiction that brings major historical events to life, with previous titles including Capone's Vault, Henry Knox's Noble Train, and Evil on the Roof of the World.
The interview offers an early look at the research behind the book, which is now available online. Hazelgrove, a national bestselling author, has been featured by The New York Times, USA Today, NPR, C-SPAN Book TV, and many other national media outlets. His books have received starred reviews from Publishers Weekly, Kirkus, and Booklist, and have been recognized with ALA Editors’ Choice Awards and Junior Library Guild Selections. He has written for The Hill, USA Today, The Smithsonian Magazine, and the Daily Mail, and has been featured on NPR’s All Things Considered. His forthcoming book is The Camp Mystic Flood: A Story of Tragedy and Heroism.
The implications of this book extend beyond the tragic event itself. It raises critical questions about the reliability of forecasting technology and emergency preparedness in the face of natural disasters. For business and technology leaders, the story underscores the need for robust risk assessment and response strategies, especially in industries operating in vulnerable environments. The flood’s aftermath, including legislative changes and lawsuits, signals potential regulatory shifts that could affect summer camps and other organizations in disaster-prone areas. Hazelgrove’s investigative approach provides a cautionary tale about the limits of technology and the enduring importance of human courage and resilience.
