It’s Halloween, the silliest and spookiest night of the year. And when Marley’s around, it’s also the messiest! This year the family is throwing a big Halloween party, and Marley wants to help with the preparations. But in typical Marley fashion, instead of helping he causes havoc. He gets his head stuck in a pumpkin, turns the streamers into confetti, eats all of the Halloween candy, and that’s just the beginning!

In this follow-up to the bestselling Bad Dog, Marley!, A Very Marley Christmas, Marley Goes to School, and Marley and the Kittens, John Grogan and Richard Cowdrey spin another web of Marley fun. Hilarious and heartwarming, this tale is perfect for trick-or-treaters everywhere.
