The Brotherhood of the Screaming Abyss
A new book by Dennis McKenna

“The McKenna brothers, Terence and Dennis, formed a Livingston and Stanley duo of argonautic exploration. And while Terence became better known as a psychedelic bard, Dennis has made an indelible mark on the world of psychoactive plants and their uses in traditional cultural and experimental settings. In The Brotherhood of the Screaming Abyss, Dennis recounts the escapades that helped to fashion the already keen minds of the two brothers. Dennis is one of the smartest guys in any room, bright, inquisitive, deeply sensitive, and in certain delightful ways a bit mad. Make sure that your seat is in the full, upright position, with your seat belt tightened low across your lap. This is a ride you won't want to miss, and there is no telling where you'll land.” - Chris Kilham
