Count up and down for Halloween fun! This humorous, rhyming book invites readers to count eerie party guests (1 to 10) as they arrive at the haunted house of the ghost. When the partygoers are frightened by a group of young trick-or-treaters, readers count backwards as the guests depart. A surprise ending offers a delightfully spooky twist. Filled with Halloween party traditions, Iza Trapani's playful art is a treat for all.
