"This book concerns a cohort of ultra-orthodox Jews based in the greater New York area who, while retaining membership and close familial and other ties with their strictly observant communities, seek out secular knowledge about the world on the down low (so to speak), both online and via in-person encounters. Ayala Fader conducted her ethnographic research in these rarified social circles for years, developing relationships of trust with the mostly young married men and women who have taken to clandestine methods to find alternative social spaces in which to question what it means to be ethical and what a life of self-fulfillment looks like. Fader's book reveals the stresses and strains that such "double-lifers" experience, including the difficulty these life choices inject into relationships with wives, husbands, and one's children. Not all of these "double-lifers" become atheists. Fader's interlocutors can be placed on a broad spectrum ranging from religiously observant but open-minded at one end to atheism on the other. The rabbinical leadership of these ultra-orthodox communities are well aware of this phenomenon and of how unfiltered internet access makes such alternative forms of seeking an ever-present temptation. (Some ultra-orthodox rabbis have been sounding the alarm for years, claiming that the internet represents more of a threat to community survival today than the Holocaust did in the last century.) Fader's book examines the institutional responses of ultra-orthodox communities to the double-lifers. These include what is typically referred to as a Torah-based type of "religious therapy" conducted by trained members of these communities who as therapists and "life coaches" blend elements of modern psychiatry with ultra-orthodoxy and "treat" troubling, potentially life-altering doubt and skepticism as symptoms of underlying emotional pathology"--
