National bestselling author William Elliott Hazelgrove is offering readers a first glimpse into the extraordinary reporting behind his forthcoming book, The Camp Mystic Flood: A Story of Tragedy and Heroism (Bloomsbury, July 8, 2027), following a wide-ranging interview on WCPT 820 Chicago with host Richard Chew.
Drawing on months of on-the-ground research in the Texas Hill Country, Hazelgrove reconstructs the catastrophic July 4, 2025 flood that claimed the lives of 146 people, including 27 young campers at Camp Mystic. Rather than focusing on blame, the book tells the complete story—from the first weather alerts to the desperate rescues, remarkable acts of courage, and the difficult questions that followed.
During the interview, Hazelgrove discussed traveling the Guadalupe River with first responders, walking the flood zone, interviewing survivors and rescuers, and examining thousands of pages of investigative reports, emergency communications, and eyewitness accounts.
Among the stories explored in the book are the minute-by-minute rise of the Guadalupe River before dawn, the final hours inside Camp Mystic as counselors and campers struggled to survive, extraordinary rescues by Coast Guard helicopter crews, first responders, neighbors, and ordinary Texans, the search that continued long after the floodwaters receded, how one of America's worst freshwater disasters unfolded despite modern forecasting technology, and the legislative investigations, lawsuits, and lasting impact on Texas summer camps.
"This is not a book about assigning blame," Hazelgrove said. "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."
Hazelgrove, author of more than two dozen books, is known for narrative nonfiction that brings major historical events to life. His previous works include Capone's Vault, Henry Knox's Noble Train, and Evil on the Roof of the World.
The complete WCPT interview is now available online, offering listeners an early look at the research and reporting behind the book. Hazelgrove's investigative approach underscores a critical takeaway: despite modern forecasting, the disaster revealed systemic failures in emergency communication and camp safety protocols. The book's exploration of these issues is vital for policymakers, camp administrators, and the public as they seek to prevent future tragedies.
By weaving together firsthand accounts and exhaustive research, Hazelgrove illuminates not only the heroism of that night but also the enduring questions about preparedness and accountability that remain relevant for communities nationwide. The Camp Mystic flood serves as a stark reminder of nature's unpredictability and the human cost when systems fail.
