The Bastard Brigade - Sam Kean
As in his other books, Sam Kean effortlessly weaves together history, science and biography into a book the recounts a lesser known story of WW2. Unlike his previous works, where each chapter is largely a stand alone anecdote, The Bastard Brigade lays out a complete narrative describing developments in nuclear physics alongside the onset and events of the war. Scientists, both famous and lesser known, become the heroes, villains, or unwilling participants in a battle for scientific and military supremacy. I highly, highly recommend this book for any Sam Kean fan, or anyone interested in learning more about the scientific frontlines of WW2.
