Zoe named the kitten Pipsqueak, because she was so tiny, and promised to always take care of her. Then the kitten grew. And grew. Now she's bigger than a horse -- and talking as well! Fleeing into the woods to escape the curious eyes of the Internet, Zoe and her best friend, Harrison, must keep the giant cat hidden as they desperately search for a way to return her to normal size. If they don't succeed, Pipsqueak may never be safe again. But why did she grow so large in the first place? And what if trying to change her back leads to even greater danger?
