Fascinating history, riveting!!
We all learn in US History classes about how WWI starts, u-boat threats to allied shipping, some east coast German Sabotage, the Zimmerman Telegram. Blum delves inside the story to weave the threads of several plots by German operatives on US soil - and it is extremely well written and captivating! I highly recommend it to all history buffs, history teachers, and other curious Minds.
