The Magic of Midnight by Aaron Christian Hahner

Halloween night, a group of unwitting trick-or-treaters find themselves in a battle with the forces of darkness. Merciless servants of evil and deception hold Halloween night itself, as their own playground. Time has stopped and this mysterious night will seemingly never end. Wishing upon a strange star grants the heroes of our fairy tale wondrous magical powers, but can they master this magic, and defeat their own fears, without falling victim to the terrifying beings known as the Shadows?
