Six years in the making, War of the Whales is the “gripping detective tale” (Publishers Weekly) of a crusading attorney, Joel Reynolds, who stumbles on one of the US Navy’s best-kept secrets: a submarine detection system that floods entire ocean basins with high-intensity sound-and drives whales onto beaches. As Joel Reynolds launches a legal fight to expose and challenge the Navy program, marine biologist Ken Balcomb witnesses a mysterious mass stranding of whales near his research station in the Bahamas. Investigating this calamity, Balcomb is forced to choose between his conscience and an oath of secrecy he swore to the Navy in his youth.
