Can't Scare Me! A Very Brave Witch by Alison McGhee
A young and properly green witch, who has never experienced the joys of Halloween on her own, does her research from the Big Book of Humans, (Humans are afraid to fly, don't like pointy hats, are rarely known to cackle, and are definitely not green) and decides to find out first hand about this whole human Halloween thing.
There's nothing too bad, except, you know, the green thing. It's time for this brave witch to take a closer look. Hang on, Kitty, we're going in!
The first thing the little witch observes is a curious human custom which sounds something like "Trick a tree." "No one can trick a tree like me!" she boasts, and circles and swoops around a likely tree in a manner which would certainly trick any tree if a tree could be tricked. This maneuver leads to an unfortunate crash landing in the middle of three costumed trick-or-treaters, a witch, a ghost, and a skeleton.
When the kid-witch approaches with a sympathetic "That was quite a spill," the young witch thinks, "Yikes. A real human! I'm being touched by a human hand!" The kid-witch adds wistfully that she has always dreamed of flying. "Have I got a treat for you," responds the little witch, and she invites the girl-witch aboard for a flying tour around the witchy mansion aboard her trusty broom.
The cheery Halloween scene, with its dark and gloomy witches' mansion, bats, ghosts, and a bright orange-striped cat waving from the little witch's broom, helps young readers see the fun of Halloween from the other side in Harry Bliss's sweet and charming illustrations for A Very Brave Witch.
