National bestselling author William Elliott Hazelgrove has completed the manuscript for The Camp Mystic Flood: A Story of Tragedy and Heroism, the first book-length narrative history of the catastrophic July 4, 2025 flood that swept through the Texas Hill Country, claiming 146 lives, including 27 girls and counselors from Camp Mystic.
Drawing on months of research in Texas, Hazelgrove traveled the length of the Guadalupe River, interviewed survivors, first responders, emergency personnel, meteorologists, local officials, and families whose lives were forever changed by the disaster. His reporting also took him into areas devastated by the flood alongside first responders, providing a firsthand look at one of the deadliest freshwater disasters in modern American history.
"The Guadalupe River appears quiet and almost impossible to imagine as a force capable of such destruction," Hazelgrove said. "But beneath that calm lies a story of extraordinary courage, heartbreaking loss, and remarkable resilience. My goal was to tell that story through the people who lived it."
The manuscript examines the events leading up to the flood, the unprecedented rise of the Guadalupe River, the desperate overnight rescues, and the months of recovery that followed. Through eyewitness accounts and extensive documentation, the book chronicles both the human tragedy and the acts of heroism that emerged during one of the worst natural disasters in Texas history.
Hazelgrove previously wrote about his research journey in a nationally published opinion essay for The Hill, describing his experience returning to the river with first responders and witnessing the lasting impact the disaster continues to have on communities throughout Kerr County.
Known for transforming historical events into compelling narrative nonfiction, Hazelgrove is the author of numerous bestselling books, including Capone's Vault: The Biggest Disaster in Television History, Henry Knox's Noble Train, and Dead Air: The Night Orson Welles Terrified America. His work has been featured by The New York Times, USA Today, the Los Angeles Times, NPR, C-SPAN's Book TV, and ABC's World News Tonight.
The Camp Mystic Flood: A Story of Tragedy and Heroism is scheduled for publication by Bloomsbury July 8, 2027. The author will appear on WCPT Chicago at 6:30 a.m. Central Time to discuss his research trip to Camp Mystic.
This definitive account offers readers a comprehensive understanding of a disaster that reshaped the Texas Hill Country, highlighting the importance of preparedness and the human spirit in the face of nature's fury. The book not only memorializes those lost but also provides critical insights for emergency management and community resilience.
