A brilliant story set in the near future and charting through several generations the emergence of psychic ability in mankind and how these gifted individuals choose to use their talents. The whole series is linked tenuously to the earlier Pliocene Saga, a series I found very poor but many find equally good. I find it hard to believe that the same author wrote both series and would ask that anyone who shares my poor view of the 'Pliocene' saga not be put off reading this book.
