Tahmima Anam's new novel is about a married couple, Cyrus and Asha, who found a tech startup. It's a social media platform that customizes ceremonies and rituals for people who aren't religious. The platform's success turns the husband into a messiah figure — even though it was his wife who designed it. We talk with Amam about how her real life boardroom experience helped inspire the novel, the allure of rituals, and her childhood growing up in many different countries.
