"The last day of October had finally arrived. The empty house at the end of the street mysteriously came to life." Oliver, the ghost who lives in that empty house, lives for Halloween! He always has a big party. To get ready, he puts dust on the furniture, welcomes the spiders, wakes up the black cats, and delivers his invitations! This time, though, one envelope goes astray and two human trick-or-treaters show up. Are treats--or tricks--in order? Simple, cartoonish watercolor and pencil illustrations complement this sweet tale of the spirit of generosity and acceptance.
