I've always thought that one reason I'm a disaster junkie is that stories of various events (airplane crashes, earthquakes, floods, fires, societal breakdown, etc.) let me "practice" what I might do in different situations. This book lets people go way past "what if" and offers solid info about how to maximize your chances of surviving a disaster.
The book is set up into three sections: Denial, Deliberation, and The Decisive Moment. Throughout, the author uses real-world examples of both failures and successes to illustrate her points, and the writing is engaging and direct. She also gives sources for more emergency-preparedness info, at sites such as reallyready.org.
In short, this is essential reading for all adults. Now I need to go watch the documentary she did on PBS in 2012.
