Scheherazade Goes West - Fatema Mernissi

While it is possible to read this book prior to reading Dreams of Trespass: Tales of a Harem Girlhood, I would recommend reading Dreams first.

This book looks at the idea of the harem from the Western male view, something which confuses Mernissi because her view of the harem is radically different (and more accurate). Her conclusions, in particular in regards to what a Western is, are interesting.
