On the morning that his father, Navy deep-sea diver Mac Macoby, dies of a heart attack, 12-year-old Robert is engulfed by the memories that tie them together. The memories come in fragments, some broken, some incomplete, but together they form the portrait of a man shaped by the tides of history, not a hero’s life but a heroic one, nonetheless. Diver is about one California family in the 1960s, and about every family, a novel about the rigors of military life amid the turbulence of the counterculture movement, a novel of how memory can fail us, serve us, and support us through loss. It is the story of an abiding love between a father and son.
