"Bobbie is on a mission. She's already survived one encounter with Logan, the jerk who attacked her village and turned her brother into a zombie. And now she won't rest until she stops his evil plan to conquer the Overworld with his zombie horde. But the closer she gets to foiling Logan, the further away she gets from her original goal: finding a cure for her zombie brother. [Meanwhile], Ben is on babysitting duty.
