Books on the Manhattan Project?

[Alatriste]

What the title says: I could use some advice on books on the Manhattan Project, i.e. not on the atomic bombs themselves or on the scientists involved. I'm looking for a work focusing on how the project was organized and managed by Groves and Oppenheimer.

And by the way, how came a mere brigade general - just promoted, to make things worse - and a walking security risk were charged with managing such a hugely vital project and spending such an enormous budget, and given such a high degree of autonomy?

this is more of a book on the morality of the issue more than anything else, but I recommend

Toungs of Conscience, R.W. Reid, Panther Books, 1969.
