Count up and down for Halloween fun! This humorous, rhyming book invites readers to count eerie party guests one through ten as they arrive at the haunted house of their ghostly host. Mummies and monsters, werewolves and witches, vampires and ghouls show up group by group to round out the festivities. These classic creatures party the night away, but when the guests are frightened by a group of young trick-or-treaters, readers count backwards as they depart. A surprise ending offers a delightfully spooky twist. Filled with Halloween party traditions, Iza Trapani's playful art is a treat for all.
