Books about Second Italo-Ethiopian war

Does anyone have any suggestions? I am mostly interested in a very detailed accounts about the war from preferably both sides or independent research of the war timeline. The only thing i found is Rodolfo Graziani's memoirs but they all available in Italian only so it barely helped.

 

I've read "Rape of Ethiopia, 1936" by A.J. Barker. It's part of Balantine's illustrated history of the violent century series. I found it an interesting read although perhaps not as detailed as you would like.
