Arnold Z. Ombee is back in this wacky, page-turning sequel to A Zombie Ate My Homework! The zombie secret is out! Sort of... Scientists at the lab that Arnold escaped from claim they've changed their tune. Instead of creating super zombie soldiers, they just want humans and zombies to be friends. Too good to be true? Probably. But Arnold agrees to help teach other zombies everything he's learned so far about being a real human boy. But there's something that seems strange about these new "zombies" (well, stranger than usual). Arnold knows it's up to him to unearth the secret before it eats him up inside. And outside. And everywhere else.
