For seven books, Clive Cussler has dazzled readers with the 'spine-tingling adventures' (Chicago Tribune) of Kurt Austin, Joe Zavala, and the rest of the NUMA® Special Assignments Team, but in Medusa the NUMA® team faces what may be its most perilous mission of all.

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.

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.
