The latest in David Poyer’s acclaimed novels about the modern Navy and Marine Corps, Onslaught chronicles Dan Lenson’s latest challenge as the U.S. Navy struggles to hold Taiwan, Korea, and Japan against a massive Chinese offensive. The prize: domination of Asia and the Western Pacific.

As the United States’ computer, satellite, and financial networks are ravaged by coordinated cyberwar attacks, China and its associated powers begin to roll up and intimidate American allies, launching invasions of India, Taiwan, South Korea, and Okinawa. USS Savo Island, captained by Dan Lenson, is one of the few forces left in its way. With a fractured crew under attack from an unknown assailant aboard their own ship, and facing missile launches from above and below the sea’s surface, can Dan and his scratch-team task force hold the line against an overwhelming enemy? Or will the U.S. lose the Pacific—and perhaps much more—to an aggressive and expansionist new Chinese Empire?
