Trick or Treat

While trick-or-treaters visit houses, Oliver, a cheerful and smiley-faced ghost is having his own Halloween party in “the empty house at the end of the street.” First appearing as gray silhouettes at the door, the party guests (skeletons, witches) all turn out to be friendly. But as the party gets underway, two unexpected guests arrive, and it’s up to Oliver to decide whether to be scary or nice. There’s nary a hint of frightfulness in Landry’s watercolors, making this a good pick for readers who like their Halloween fare on the mild side. Ages 4–8. (Sept.)
