Query: You've got to be kidding, right?

The late Philip K. Dick was a genius. He wrote 6-8 masterpieces, which should be required reading for anyone with some interest in science fiction.However, he also wrote some plain awful novels in order to make a living. In general, the books he wrote in the 1950s are his worst with Vulcan's Hammer being his worst published novel ever (in my opinion). The story is flimsy and dull...one of Dick's biographers (Lawrence Sutin) also cites it as probably being his worst book.I'm only writing this review because I just can't believe the number of positive reviews for this book. If "Man in the High Castle", which is probably Dick's best work, deserves 5 stars... then by that scale, Vulcan's hammer deserves a 0.5.The fact that this book was even reprinted is a shame...a real waste of paper.
