A surprisingly nice attempt at integrating psychedelic concepts into a sci-fi/fantasy novel. Wisman alternates between telling the story of Eden, and occasionally breaking out to write about his own use of “a powerful chemical substance”. He never names this psychedelic material, but describes his frequent work with it and the thoughts and philosophical meanderings he experienced while under its effects, which he incorporates into the Eden story. Eden itself incorporates some of the concepts encountered during his own trips, but also explicitly weaves into the story some standard psychedelic concepts and debates. My primary complaint was that the story is a little short on character development. I would have liked it to be another 50 pages longer to explore the depths of the characters a little more fully. All in all an enjoyable book, unique in its format and genre, primarily targetted at those who enjoy sci-fi/fantasy AND have an interest in psychoactive drugs and their effects.
