One of the best science fiction books I’ve read in many years. Resonance is right up there with the best of Arthur C. Clarke and Isaac Asmov. AJ Scudiere creates a plot of alternate universes and a reversal of the earth’s polarity in which nothing is quite as it seems and yet it is all so much more than it should be. You won’t be able to put this book down once you start it. It moves like lightning and you will be confused at times but you’ll be compelled to keep reading. Now that I’ve finished it, my first task is to find other titles by AJ and lose myself once again.
