When composer and Bard College music professor Margaret De Wys learned she had breast cancer, the diagnosis shattered her comfortable life. Seized by fear, crushed by existential loneliness, she couldn't respond when her loved ones reached out to her. To everyone's concern, the illness propelled her away from her family and deep into the Amazon to work with Carlos, a charismatic Shuar shaman and master of medicina milenaria, an ancient mystical tradition with a highly sophisticated and precise technology of healing. In Black Smoke, De Wys writes of her amazing encounter with Carlos as he guided her into a world of potent visionary plants, harrowing initiations, ritual purification, and miraculous healings, including the complete disappearance of her cancer. It was, as Carlos called it, "the path of the warrior."

Sharing a journey not only through cancer but also through self-transformation, De Wys provides an intimate inside look at the shamanic ceremonies of ayahuasca and the ways this spiritual medicine can heal the emotional origins of disease now plaguing our modern technological culture. Capturing her physical, emotional, and "holy voyage" through a world that differs vastly from our own in its perception of healing and wholeness, she offers a revealing chronicle of spiritual insight and a trenchant exploration of the limits of idealism. She not only provides a probing look at how our society can learn and benefit from indigenous wisdom but also weaves a cautionary tale about how potentially dangerous it is--on both sides--to try to cross those frontiers.
