Forensic pathologist Joanna Blalock returns in an explosive new medical thriller!

When Los Angeles forensic pathologist Joanna Blalock is tapped to investigate a deadly new bacteria currently on a Navy ship off the coast of Alaska, she is both excited by the challenge and apprehensive about the dangerous and claustrophobic working environment at sea. Joining a team of world-class scientists, she finds the atmosphere is scary enough, but it gets worse when several suspicious deaths lead Joanna to believe that there is a ruthless killer on board who may be responsible for the entire disaster. The horror of her discovery pales, however, when the entire ship is quarantined and Joanna is plunged into a desperate fight for survival -- pitted against both man and microbe -- with the fate of humanity in the balance!
