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® 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.
