And the priest shall go forth out of the camp; and the priest shall look, and, behold, if the plague of leprosy be healed in the leper;
Leviticus 14:3 KJV
My major preoccupation is the question, ‘What is reality?’ Many of my stories and novels deal with psychotic states or drug-induced states by which I can present the concept of a multiverse rather than a universe. Music and sociology are themes in my novels, also radical political trends; in particular I’ve written about fascism and my fear of it.
