Jet's Reviews: The Making of the Atomic Bomb

While I loved this book, I will also admit it is not an easy or fast read.  It goes into the details, the nitty-gritty, and sometimes that makes it a bit dry.  And it's long.  But this is also what makes it so great - when you finish, you really truly feel like you've become an expert on the history and some of the science behind the making of the atomic bomb.
