"The volume's scope is impressive, its structure is cogent and complementary, and its contributors offer approachable analyses of deconversion and disaffiliation. Readers new to the field will encounter accessible explanations of basic concepts and core debates, while those familiar with scholarship on apostasy will find a battery of case studies to examine and challenges to meet." - Kristian Klippenstein , in: Nova Religio 24:1, 2020. "The anthology takes a broad approach, encompassing historical debates on topics of conversion, contemporary case studies from a range of traditions, including established institutions like Catholicism, new religious or spiritual practices like Vipassana meditation, asylum seekers leaving Islam for Christianity, and chapters approaching the topic from a range of subfields within religious studies. (.) The anthology offers a berth for studies that are topical and important. (.) I would still recommend this book to religious studies scholars looking for a work dealing with the complexities of religious identity in historical and contemporary contexts, who are also interested in a handbook for undergraduate students introducing the available methodological and theoretical approaches within religious studies.

"Now that the study of conversion has a well-established niche in religious scholarship, it is only natural that the reverse phenomenon, namely the study of 'deconversion' ('disaffiliation', 'losing religion'), should emerge. This volume indicates clearly that this developing field of inquiry can yield significant insights into the dynamics of the contemporary religious scene. (.) By drawing attention to the need to study the phenomenon of leaving religion, by providing an impressive range of intriguing case studies, by highlighting the problems encountered by scholars engaging in such studies, and by suggesting theoretical and methodological ways of addressing these problems, the entire volume provides nothing less than an initiation into a promising field of inquiry taking shape within the academic study of contemporary religion." - Theodore Pulcini , Dickinson College, USA , in: Journal of Contemporary Religion , 35:3 (2020).
