From the Belly of the Dragon — Mark Mynheir

Caught in a Cult People associated with him have been killed, but Dr. Walter Simmons is a successful man. His books and tapes incorporate psychological principles with New Age, feel-good spiritualism and are a hit on college campuses. But when his top students join him for an intensive "training" program, they are actually joining a dangerous cult. Florida Department of Law Enforcement Agent Tim Porter's daughter, Ruby, is lured in like the rest, the heights of a dream plummeting her to the depths of a living nightmare. Tim and his ex-wife are driven to their knees for their daughter. But what about Ruby? To what lengths can they go to rescue her from Dr. Simmons's clutches? Complicating matters is an FBI investigation, a corrupt chief of police, and a mounting spiritual battle. How much time do they really have?
