Medusa

In the Micronesian Islands, a top secret, U.S. government- sponsored undersea lab conducting vital biomedical research on a rare jellyfish known as the Blue Medusa suddenly . . . disappears. At the same time, off Bermuda, a bathysphere is attacked by an underwater vehicle and left helpless a half mile below the surface, its passengers-including Zavala-left to die. Only Kurt Austin's heroic measures save them from a watery grave, but, suspecting a connection, Austin puts the NUMA(r) team on the case. He has no idea what he's just gotten them all into. A hideous series of medical experiments . . . an extraordinarily ambitious Chinese criminal organization . . . a secret new virus that threatens to set off a worldwide pandemic. Austin and Zavala have been in tight spots before, but this time it's not just their own skins they're trying to save-it's the lives of millions.
