"Off the Derech," translated as "Off the Path," is the term used within the Orthodox Jewish community to describe those who have left Jewish observance. This groundbreaking book by Faranak Margolese examines why Orthodox Jews stop practicing Judaism, confronting one of the most pressing issues in the religious Jewish world today. Based on a study which involved over 500 Jews who left Orthodox Judaism, Off the Derech presents the first comprehensive examination of the causes of defection from Orthodox Judaism. It clearly and thoroughly explains those causes, and provides solutions to this increasingly common phenomenon. In doing so, Off the Derech enlightens not only the Orthodox but Jewish parents and leaders from all streams of Judaism as the research provides valuable insights into assimilation and Jewish continuity at large. This highly anticipated work, over five years in the making, became an instant Jewish best-seller and is considered the definitive handbook on the off the derech phenomenon. It is a must-read for parents, teachers and Rabbis alike.
