Interesting and original setting with the adorable flavour of a science fiction future dreamed up a few decades ago - mega-computers, telepathy, gardening on Mars and phone booths all happily co-existing. The plot has some moments of real suspense, until it is all solved in the end with the All-Powerful Magic Trick That Wasn't Even Mentioned Before. The themes are interesting, but somewhat obscured by the Freudian dream sequence psychedelia stuff.
