Cults and New Religions offers an overview of the history and development of eight new religious movements in the late twentieth century: the Church of Scientology, Transcendental Meditation, Unificationism, The Family International, the Ramtha School of Enlightenment, the Branch Davidians, Heaven's Gate, and Wicca.

The book profiles each new religion, describing its origins, doctrines and rituals, leadership and organization. Each chapter includes a discussion of one of the major sources of controversy surrounding these movements, controversies that have led to them being popularly regarded as "cults": whether they are indeed authentic religions, the validity of claims that brainwashing techniques are used to gain and retain members, their potential for violence, the implications of experimentation with unconventional sexual practices, and the deeply rooted cultural fears they engender
