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.
