What the reviewers are saying:

"This is an outstanding work, and an important book, as it represents the first real telling of this story based upon original German source materials, including U-boat deck logs, war diaries, official German government records, and letters and correspondence from U-boat captains and crew members, most of which represents completely new information... Reaping the Whirlwind [is] clearly the best book in its class, and a must-have for any serious student of American military history." - John R. Barrows, Monmouth Timeline

"Thoroughly engrossing and valuable to any reader or researcher attempting to comprehend and untangle the events off the North American Coast during WWI. If you're interested in U-boats, US East Coast naval history, or even just WW1 at sea, you cannot go wrong with this book." - Haze Grey History

"...an impressive research tour de force that will appeal not just to those interested in the First World War and naval warfare, but also American local history buffs focused on its East Coast and us Western Europeans accustomed to seeing periscopes only around the United Kingdom." - Alexander van der Biest, Paper Can Reviews

"This book is an admirable undertaking and quite an intensive one at that. Translating U-boat logs can be tedious and dull, but this is quite a readable account." - Russ Lockwood, Historical Miniatures Gaming Society
