Zombies never stay dead. Winter Hawk is on day three of a five-day cruise when the zombie infection decides to make its appearance. She's seen her share of bad days, but nothing compares to the fact that the people around Winter are dying and coming back to life in droves. Winter has to get off of the cruise ship and away from the infection, no matter what it takes. Armed with a first aid kit, a couple of water bottles, and a few unlikely companions, she embarks on a journey that will change everything. If she can manage to survive.
