Zomboyage!

With the whole world zombifying around them, Zack, Rice, Zoe, Madison, Ozzie, and Olivia flee the infested coast of Florida in search of help. There's only one person who can save them: an oddball explorer who knows the key to the antidote . . . but he has escaped to a zombie-proof bunker somewhere in the Caribbean. As they take to the high seas in search of the secret antidote ingredient, they must battle the scariest seafarers of all: super zombie pirates and undead killer sharks.

Will the Zombie Chasers survive the undead seas, or are they destined to become shark bait
