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.
Filled with the high-stakes suspense and boundless invention unique to Cussler, Medusa is the most thrilling novel yet from the grand master of adventure.
