"Oscar Ollie Brown is on the hunt! Ants and frogs and cows are making his life miserable and he's determined to put them in their place. There's just one problem: they're invisible. And poor Oscar! His life is plagued with creatures he can't see. A cow licks his head every night, and that's just for starters. He's also had ants in his pants and a frog in his throat, but try as he might, he can't seem to find them. Even so, he knows they're there. How? Because his mother tells him so!"

Ages 6 to 12.
