Mystical paths - Susan Howatch

1968, with the swinging sixties sliding into decadence, finds Nicholas Darrow wrestling with overwhelming personal problems: How can he bring himself to marry his fiance, Rosalind, when he is unable to avoid promiscuity? How can he become a priest when he finds it so difficult to live as one? And how can he break his dangerous dependence on his father Jon, whose psychic gifts he shares?
It is at this crucial moment in his life that Nick becomes involved in the mystery surrounding his friend, Christian Aysgarth. Gradually, he realises that discovering the truth about this enigmatic and complex man will unlock the answers to his own baffling problems. However, his journey through darkness into the light reverses all the old certainties and, in his experiments with the psychic powers, Nick risks even his own life and sanity.
