What happened during the 1900 Galveston hurricane is told mostly through the U.S. Weather Bureau's weatherman in Galveston at the time, Isaac Cline. The intent is to show how the weather service was at fault for the terrible death toll in Galveston. The highest levels of the service so controlling that the word hurricane was not allowed. Isaac Cline himself claimed the physics of hurricanes allowed only occasional mild hurricanes as far west as Galveston.
For a book about real people, this book has constant assumptions about peoples' feelings that make me uneasy. The author did do a lot of research and his sources are all listed, with reasons for some of the assumptions, but they are too specific. The book starts out saying "On some nights, however, the children cried only long enough to wake him, and he would lie there heart-struck, wondering what had brought him back to the world at such an unaccustomed hour. Tonight that feeling returned. Most other nights, Isaac slept soundly." I am comfortable with this in a novel, but not in a non-fiction book.
The book jumps around between different time periods and different characters so much that the thread of the hurricane's development gets lost. On the other hand, this does give a sense of how the hurricane effected more than just 1 part of the city, and gives some perspective on historical hurricanes, but less would be better.
The history of how people learned the causes of hurricanes is some of the best parts of the book, along with some of the weird weather phenomena.
There are 2 maps at vastly different scales, but even more would help.
