Which book is the best for understanding the Riemann hypotheses?

[khil_phys]

I'm looking for a semi-popular book on the Riemann hypotheses, on the scale of Derbyshire's book. It seems that Derbyshire and Edwards are the best in this area. Which one should I go for? The content must be quite extensive. Please suggest other ones too...

i think at least edwards' book has a translation of riemann's paper. I recommend reading riemann more than these books.
