This reference begins with the Allies’ fears that Germany would be the first to create the atomic bomb and then proceeds through the steps taken to make sure the Allies beat them to it. From the selection of the scientists and the military commander in charge of the project to the selection of the facilities where the work would take place, Wukovits provides clear information, interesting sidebars, and photos to give students insight into this devastating event in history. The majority of the book details the planning and construction of the bomb; information on Hiroshima and Nagasaki is included although more detail is readily available elsewhere.  While the book does touch on the opposing views on whether atomic bombs should be used, it is not explored in depth here. This resource does a good job illustrating the planning and execution of the creation of the bomb.
