After graduating from university, Willow Wilson, a young American - and newly converted Muslim - impulsively accepts a teaching position in Cairo. There, she meets Omar, a passionate young nationalist with a degree in astrophysics. Omar introduces Willow to the bustling city, and through him she discovers a young, moderate nationalist movement, a movement that both wants to divest itself of western influence and regain cultural pride. When the two find themselves unexpectedly in love, despite their deep cultural differences, they decide that they will try to forge a third culture, a new landscape that will embrace some of each of their cultures, and give their fledgling romance some hope of survival.

Wilson weaves this engaging personal story with deep insights into faith in a fractured world, and gives westerners rare insight into an important young reform movement. Butterfly Mosque is an inspiring account of an unlikely cross-cultural love, and the moving story of two young people working within the boundaries of contemporary religion and culture to forge a life together against the odds.
