City of Seven Rivers is historical fiction set in 1995 about a Marin County junior high student who suspects that Myron Hunter, the 74-year-old recluse next door is in fact Arden Hennessey, former bombardier on the Enola Gay.  The boy’s suspicions counter the widely held belief that Hennessey, whose postwar success as a painter would nearly be undone by unrelenting guilt over the death and destruction he himself unleashed upon Hiroshima, leaped off the Golden Gate Bridge on the 10-year anniversary of the bombing.
