Would you kindly recommend a book for me?

For my final project in my historiography class I have to make a powerpoint presentation that compares the usefulness of film media and written text. The movie my partner and I have to watch is Casablanca, so I thought I could select a book about the Vichy Moroccan government or about the African campaign of WWII in general. The problem is, I can’t find any decent books on the subject. That’s where you come in, Fluther.

Can you recommend a preferably short book on the subject of Morocco during WWII, or just Africa in WWII in general?

I’m not asking for you to do my homework for me, I’m simply asking for any recommendations. I know there are a lot of hardcore readers on Fluther, so I figured this would be a good resource for suggestions. Thanks in advance.
