A hilarious, rhyming counting book that is perfect for Halloween! Young trick-or-treaters will learn to count backwards from ten to one as each ghost flies away to the woods after seeing a gleaming skeleton, a bat black as night, a frightening hoot owl, or an enormous rat -- just a few of all the witch's tricks. But one clever ghost, before flying away, unravels the witch's plan! Together, the ghosts rise up against the witch in a big, scary BOO!Jennifer O'Connell's wacky yet mysterious illustrations lead the reader through the ghosts' dilapidated mansion.
