Just want to put out there that the book Bomb, by Steve Sheinkin is VERY good. My sons and I, (11 and 13) all loved it, as did the book club that they were in. It is about the making of the Atom Bomb, the espionage, the scientists, the people trying to keep track of it all and how the bomb came to fruition....and the excitement when it worked, followed by depression when they realized what it meant.

It is non-fiction, but is written in a very engaging manner that appeals to the reader. Sheinkin used to write text books, but has reformed. Not text bookish at all.
