Martian Time-Slip … describes a desolate, end-of-the-century Mars inhabited by doomed clairvoyants, an obsessed tycoon and an autistic child-hero who together move through a landscape that uncannily resembles southern California perceived through the glaze of some deep psychosis…. [The] novel is full of incident, fusing terror and comedy in a unique way. More than any other SF writer, Dick is able to convey the sense of everyday reality as totally threatening. (p. 879)
