I got this book at Target, which tends to cater to book groups, and this seems to me to be an excellent book group book. It was a fairly easy and fast read but very well written. The chapters are divided by event and further into sections which are written by the different women. Sometimes there are excerpts from their conversations between the sections which allows the reader to hear the interaction between the three women.
They bond over chocolate, their children, and chandeliers (Ranya and Priscilla have the same one hanging in their respective homes), but they don't ignore the tough stuff either. Priscilla and Suzanne butt heads over the cruxifiction; Ranya talks about her family's Palestinian roots; all three undergo their own unique crises in the book. After all, these three New Yorkers came together after 9-11.
Writing a book with three authors isn't easy, but they make it look simple and the book flows very well. But in the end what makes this book compelling is that it gives the reader a chance to see three women from three different religions from a personal angle. After reading this I felt like I understood the followers of all three religions better. Definitely recommended.
One caveat to the recommendation, this book is definitely geared more towards women, particularily women with children and out of school. So teen boys, for example, likely wouldn't connect with it as well as a book group mom.
