Another Day At the Mall

From publisher blurb:

As employees in the super-collossal mega-big Mall of the West, the characters think they've seen it all - until the zombies break out of the Makeup World Outlet and try to eat them. But as the sign over the mall entrance reads, "THE FUN NEVER STOPS!" Before the day is done, they'll face a ruthless corporate coverup, merciless security guards, a top-secret bioresearch lab and all the freak-painted undead they can possibly stand. But after all is said and done, it's just another day at the mall...
