Author and mental health counselor Steve Hassan has made hundreds of television appearances in recent years to spread the alarm about the dangerous growth of "cults" in America. A former top lieutenant to the Rev. Sun Myung Moon -- the charismatic founder of the Unification Church, the fanatical South Korean religious group known popularly as the "Moonies" -- he clearly knows the perils of such groups from the inside. In Freedom of Mind, his fourth book, he presents an updated version of his practical handbook published in 2000 on how family members can approach and successfully "rescue" their loved ones from the clutches of groups that nurture extreme emotional and psychological dependency among their members to the point where many are prepared to do anything -- even commit mass suicide -- to fulfill their leaders' mission.
