From publisher blurb:
You barely survived the outbreak aboard the Pinnacle cruise ship as the rest of the passengers and crew became Living Dead. After escaping in a mercenary craft that was damaged during the final battle against the zombies, you managed to ride the waves back to the United States, coming upon a small marina.
Although the place is deserted, a brief encounter with the Living Dead proves that whatever is happening wasn't just confined to the cruise ship.
But can you survive when a new enemy rears its head? An enemy far, far more dangerous than the Living Dead?
