Saz has been hired by a mystery employer, the Wavewalker, to investigate the activities of Dr Maxwell North, an internationally acclaimed therapist, healer and guru. She starts by experiencing "The Process" at a meeting in London, then insinuates herself into North's life and home, not realising the extent to which North will go to protect the dark secrets of his past. Starting in '70s San Francisco, then crashing into her own '90s London life, the investigation propels Saz into dangerous territory and a highly combustible conclusion.
