National bestselling author William Elliott Hazelgrove is shedding new light on the catastrophic July 4, 2025 flood that devastated the Texas Hill Country and claimed the lives of 146 people, including 27 young campers at Camp Mystic. In a recent interview on WCPT 820 Chicago with host Richard Chew, Hazelgrove shared insights from his forthcoming book, The Camp Mystic Flood: A Story of Tragedy and Heroism, set for release by Bloomsbury on July 8, 2027.
The book is the result of months of on-the-ground research, during which Hazelgrove traveled the Guadalupe River with first responders, walked the flood zone, and interviewed survivors, rescuers, and investigators. He also examined thousands of pages of investigative reports, emergency communications, and eyewitness accounts to piece together the full narrative of the disaster. Rather than focusing on blame, the book aims to tell the complete story, from the first weather alerts to the desperate rescues and the difficult questions that followed.
Among the revelations 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, and the extraordinary rescues carried out by Coast Guard helicopter crews, first responders, neighbors, and ordinary Texans. The book also explores 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."
The interview on WCPT provided an early look at the research and reporting behind the book, and the complete interview is now available online. Hazelgrove, who has authored 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 Camp Mystic flood has been a subject of national scrutiny, raising questions about emergency preparedness and the adequacy of warning systems. Hazelgrove's book is expected to reignite discussions about how to prevent similar tragedies in the future, particularly in regions prone to flash flooding. The disaster also had a profound impact on the summer camp industry in Texas, prompting many camps to reassess their safety protocols and evacuation plans.
As the one-year anniversary of the flood approaches, Hazelgrove's work serves as a sobering reminder of the power of nature and the resilience of the human spirit. The book is poised to become a definitive account of the tragedy, offering readers a detailed and humanizing look at the events that unfolded that fateful morning.
