Publisher's Synopsis
In the Micronesian Islands, a top-secret, US 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. Stranded half a mile below the surface, its passengers are left to die. Only Kurt Austin's heroic measures can now save them from a watery grave. Austin, suspecting a connection between the two events, puts the NUMA team on the case but he has no idea what he has just got them all into. Austin and NUMA have been in tight spots before, but this time it's not just their own skins they're trying to save...
