His other Wife by Umm Zakiyyah

Jacob is a successful businessman and college professor, and his wife Deanna is a renowned marriage counselor and author. Together they are their Muslim community’s power couple. Aliyah is Deanna’s recently divorced best friend who has just accepted a position at the college where Jacob works–and who is the unwilling recipient of Deanna’s constant unsolicited relationship advice, particularly that Aliyah needs to learn how to hold a marriage together and keep a man from ever thinking about marrying another woman. But their friendship takes a difficult turn when Aliyah receives a phone call from her uncle saying that Jacob is interested in marrying her as a second wife–without Deanna’s knowledge.
