This book is a definite head trip. The first 2/3rds of it are easy to follow, the story of a materialistic society, degradation of the earth, colonists using hallucinogens to escape their dreary lives, with some other colonists (mainly only mentioned) turning to religion. The industrialist Palmer Eldritch has returned from an extra solar space trip with a new drug, one that promises a better experience, claiming that one can become a God in during their hallucination, or at least experience the divine. Naturally, the makers of Can-D want to stop Palmer and preserve the market, and this drives the story forward. The latter 1/3rd of the book is more ambiguous, as often in his works, it can be interpreted in different ways, but to say anything more would spoil the story too much. The story itself is definitely thrilling--it had me glued to the point where I read most of it in one sitting.
