Jump City is full of strange, shambling creatures muttering about sales and dead set on brains. The Teen Titans saw a comet fall from the sky and can think of nowhere better to hang out and see what happens than the mall. If their theory is correct and people start turning into zombies, they want to be prepared-and we all know zombies love the mall! But as the situation grows ever more dire, Robin and his team take to the streets, trying to save the city from the bargain-hungry undead. But these zombies really bite: the cemetery isn't safe, the H.I.V.E. Five are not alive, and Robin's teammates are about to succumb to shopping fever! Can Robin keep it together long enough to cancel this apocalypse?
