Brotherhood of the Screaming Abyss

This book chronicles the McKenna brothers’ childhood in western Colorado during the 1950s and 1960s, including their adolescent adventures and first encounters with alcohol and drugs.

It weaves personal narrative through philosophical ideas and tales of psychedelic experimentation, such as the 'Experiment at La Chorrera'.

Dennis McKenna reflects on his early interests in cosmology and astrology, his sometimes rocky relationship with his older brother, and their diverging paths later in life.

The book also includes accounts of their mother’s and Terence’s battles with cancer and Dennis’s reflections on scientific revelations, climate change, and social and political crises in the 10th Anniversary edition.
