"A well-balanced and authentic view of David—where he came from, who he was, what the influences on his worldview were, and especially his sense of urgency about the unfolding situation at Mount St. Helens in spring 1980. Volcanoes are complex features; Melanie Holmes explains scientific ideas in a clear, straightforward manner that makes them more accessible to a broad, nonspecialist audience."--Tom Casadevall, former acting director for the U.S. Geological Survey

"Read this book--you will receive an excellent and understandable description of a volcanic eruption and a moving chronicle of the making of a geologist from a boy to a man."--Vicki S. McConnell, former State Geologist of Oregon

"In this compelling book about volcanologist David Johnston, Melanie Holmes takes the reader from the cold war and Vietnam days of Midwest America to the short fuse lit in 1980 under Mount St. Helens. Dave’s story is well worth telling, and Holmes does so with skill, honesty, and concern for accuracy."--Barry Voight, Penn State University

"The intertwined personal life of David Johnston with Mount St. Helens geology and the challenges of dangerous research have, in this story, produced an incredibly engaging saga. A beautiful tribute to a scientist and to science."--Robbie Rice Gries, author of Anomalies: Pioneering Women in Petroleum Geology: 1917–2017 and president of the Geological Society of America

"Anyone who aspires to be a scientist or is curious about the wonder and fury of volcanoes will be inspired and mesmerized by Dave's story of courage and selflessness in the pursuit of knowledge to protect all of us from harm."--Christine McEntee, CEO/Executive Director of the American Geophysical Union

"This wonderful book has several subjects; volcanology, natural disasters and human behavior, heroism, and the life of one particular man. This is an engrossing read that is absorbingly suspenseful, despite the fact that readers know the outcome. David Johnston, the hero of the story, is a multi-dimensional, complex character. Holmes shows an understanding of human psychology and has a gift for evoking personality with a few verbal gestures. We come to know David Johnston and the part he plays in the human drama surrounding Mount St. Helens. Unforgettable."--Mary V. Dearborn, author of Ernest Hemingway: A Biography

"David Johnston was a young man who explored; he wanted to know more. He died in the service of that knowledge--nothing less than a hero in this regard. There have been a number of memorials, all fine and well-deserved. None is better than this book. It finds a fascinating story. It tells the story well. And nothing more could a reader wish."--Zay N. Smith, former Chicago Sun-Times columnist, award-winning journalist, and coauthor of The Mirage
