@dlowan,
His latest collection is called
Fun With Problems. His last novel was called
Bay of Souls. My favorite novel of his is the Middle Eastern thriller
Damascus Gate. His lead characters of these two novels are both intellectuals caught in their own spiritual journeys. Both are critiques for and against religion.
Ordinarily the slow, meandering and spiritual-heavy dialogue in
Damascus Gate between the two main characters: the agnostic protagonist and a girl who has been recently recruited into a fundamentalist Christian terrorist group somehow involved in a future plot in Jerusalem would have me putting the book down indefinitely. But
Robert Stone written it as a compelling page turner. Difficult to explain how he manages it but the ending was quite impressive. I don't want to give anything away but the ending with its incredible twist would fit in with much less intellectual savvy ... no ... it would put these Hollywood action films to shame.
