1980, Mississippi. It is three in the morning when Bobby Western zips the jacket of his wet suit and plunges into the darkness of the ocean. His dive light illuminates a sunken jet, nine bodies still buckled in their seats, hair floating, eyes devoid of speculation. Missing from the crash site are the pilot's flight bag, the plane's black box ? and the tenth passenger . . . Now a collateral witness to this disappearance, Bobby is discouraged from speaking of what he has seen. He is a man haunted: by the ghost of his father, inventor of the bomb that melted glass and flesh in Hiroshima, and by his sister, the love and ruin of his soul.
