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 mysterious events, puts the NUMA team on the case. He
has no idea what he has just got 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 world-wide pandemic.
Austin and NUMA 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.
