The Great Deluge delivers extensive detailed accounts of the experiences of individuals involved with Post-Katrina rescue and relief efforts. It is the most comprehensive of the various books on this subject that I have encountered. Reading this book provided me with a gentle catharsis. As a member of an assessment team sent to Gulf Coast about a month after Katrina devastated the area, I've been laden with the burden of many wrenching tales that have largely gone unreported. This book contains a wealth of very specific and well-documented reports. First-hand accounts of personal experiences results in a certain amount of repetition, and that's as it should be. Each set of eyes sees individually, and the consistency of these accounts bolsters credibility. This book should be required reading for anyone choosing to present themselves as knowledgeable with regard to anything Katrina-related. It's not a pretty picture. It is a compelling account of who we are as a nation.
