Ted and Tippy are twins. Ted is an outgoing, good boy, while Tippy loves adventure—and mischief. Her pranks grow bolder and crueler, until one day she goes too far. Thrown from a horse, the two become ghosts, and Ted finally gets to be the bossy one. But what are they to do now? Then the twins’ family moves away, and the unhappy pair find another spook living in their house! Blackie looks much like themselves, but dark. And he doesn’t like the twins invading his world. Tippy laments her mistake and swears she’d be a good girl, if only she could do it over. Will the twins ever find their parents? Will Blackie have a change of heart and help the twins? Can they all get a second chance?
