A fast-paced and engaging story about alternate realities, drug abuse, and living in a police state (all of which are prominent themes in Dick’s other novels and short stories). I’m surprised this one hasn’t been made into a movie yet, considering so many of Dick’s other works have been adapted. Undoubtedly, Dick was one of the best and most original science fiction writers of the 20th century, and “Flow My Tears” is one of his best.
